The addition polymers of the present invention can be prepared via standard free radical solution polymerization methods that are well- known by those skilled in the art. Typical free radical initiators are peroxygen compounds azo compounds and persulfates. Free radical initiators include, for example, benzoyl peroxide, t-butyl diperphthalate, perargouyl peroxide, 1 -hydroxycyclohexyl hydroperoxide, dialkylperoxides, diacylperoxides, azodiisobutyronitrile, and dimethylazodiisobutyronitrile. Suitable solvents include alkanes such as pentane, hexane, octane, nonane, and decane, cycloalkanes such as cyclohexane, cycloheptane, cyclooctane, decalin, and norbornane, aromatic hydrocarbons such as benzene, toluene, xylene, ethylbenzene, and cumene, halogenated hydrocarbons such as chlorobutane, bromohexane, dichloroethane, and chlorobenzene, and organic solvents such as ethyl acetate, n-butyl acetate, isobutyl acetate, methylproionate, and THF. Free radical polymerization techniques are set forth in the Encyclopedia of Polymer Science, John Wiley & Sons, 13, 708 (1988). When copolymerizing maleic anhydride, SO 2 , and CO into the polymer backbone free radical polymerization is the preferred route. Alternatively, and preferably, the polycyclic monomers of this invention are addition polymerized in the presence of a catalyst represented by the formula: E n Ni(C 6 F 5 ) 2 wherein n is 1 or 2 and E represents a neutral electron donor ligand. When n is 1 , E preferably is a π-arene ligand preferably selected from toluene, benzene, and mesitylene. When n is 2, E preferably is selected from diethylether, tetrahydrofuran (THF), and dioxane. The ratio of monomer to catalyst (based on nickel) in the reaction medium preferably ranges from about 2000: 1 to about 50:1. The reaction can be run in a hydrocarbon solvent. Preferred solvents include cyclohexane, and toluene. The reaction can be run at a temperature range of from about 0°C to about 70°C, preferably from about 10°C to about 50°C, and more preferably from about 20°C to about 40°C. Preferred catalysts of the above formula include (toluene)bis(perfluorophenyl) nickel, (mesitylene)bis(perfluorophenyl) nickel, (benzene)bis(perfluorophenyl) nickel, bis(tetrahydrofuran)bis(perfluorophenyl) nickel, and bis(dioxane)bis(perfiuorophenyl) nickel. The norbornene-type monomers of Formula I, II, III and IV can alternatively be polymerized via ring-opening metathesis polymerization (ROMP). The ROMP polymers of the present invention are polymerized in the presence of a metathesis ring-opening polymerization catalyst in an appropriate solvent. Methods of polymerizing via ROMP and the subsequent hydrogenation of the ring-opened polymers so obtained are disclosed in U.S. Patent Nos. 5,053,471 and 5,202,388 which are incorporated herein by reference. In one ROMP embodiment the polycyclic monomers of the invention can be polymerized in the presence of a single component ruthenium or osmium metal carbene complex catalyst such as those disclosed in WO 95-US9655. The monomer to catalyst ratio employed should range from about 100: 1 to about 2,000: 1 , with a preferred ratio of about 500:1 (based on ruthenium or osmium metal). The reaction can be conducted in halohydrocarbon solvent such as dichloroethane, dichloromethane, chlorobenzene and the like or in a hydrocarbon solvent such as toluene. The amount of solvent employed in the reaction medium should be sufficient to achieve a solids content of about 5 to about 40 weight percent, with 6 to 25 weight percent solids to solvent being preferred. The reaction can be conducted at a temperature ranging from about 0°C to about 60°C, with about 20°C to 50°C being preferred. A preferred metal carbene catalyst is bis(tricyclohexylphosphine)benzylidene ruthenium. Surprisingly and advantageously, it has been found that this catalyst can be utilized as the initial ROMP reaction catalyst and as an efficient hydrogenation catalyst to afford an essentially saturated ROMP polymer. No additional hydrogenation catalyst need be employed. Following the initial ROMP reaction, all that is needed to effect the hydrogenation of the polymer backbone is to maintain hydrogen pressure over the reaction medium at a temperature above about 100°C but lower than about 220°C, preferably between about 150°C to about 200°C. The addition polymers of the invention comprise repeating units of the formula: wherein x independently represents oxygen, nitrogen, sulfur or a methylene group of the formula -(CH 2 )„— ; n' is an integer of 1 to 5, preferably 1 or 2, and more preferably 1 ; n is an integer from 0 to 5; and R 1 and R 4 independently represent hydrogen, linear or branched linear and branched C 1 -C 20 alkyl; R and R independently represent hydrogen, and linear and branched C1-C 20 alkyl, with the proviso that at least one of R and R 3 is a pendant cyclic anhydride group of the formula: or at least one of R 1 and R 2 or R 3 and R 4 is be taken together with the ring carbon atom to which they are attached to form a spirally bonded cyclic anhydride group. Preferred repeating units under Formula lb are represented below: wherein x, m and n' are as previously defined. In another embodiment of the invention the polymer comprises repeating units of Formula lb and repeating units of Formula Ilia below: 0 1 wherein R to R , x, and m are as defined previously. Preferred repeating units of Ilia are selected from one or more of the repeating unit structures under Formulae 1Kb and Hie below: wherein x, and m are as previously defined, n' is and integer from 0 to 10, and R 13 and R 14 are as defined previously. Repeating units containing pendant sulfomamide groups are represented by Formula Ila below: wherein x, m, and R to R are as previously defined. Repeating units containing pendant hydrocarbyl groups are represented as Formula Via as follows: wherein x, m, and R 16 to R 19 are as previously defined. Polymers comprising repeating units of Formula lb and IIIc are useful in photoresist applications. These polymers can further comprise repeating units selected from Formulae II, III, IV, maleic anhydride, SO 2 , CO, and combinations thereof. The ROMP hydrogenated polymers of the invention comprise repeating units of the formula: 18 wherein x, m, and R to R 4 are as defined previously. A ROMP polymer contains a repeating unit with one less cyclic unit than did the starting monomer. Accordingly, the repeating units derived from the monomers set forth under Formulae II, III and IV will have similar ring opened repeating unit structures as in Formula Ic above. The photoresist compositions of the present invention comprise the disclosed polycyclic compositions, a solvent, and an photosensitive acid generator (photoinitiator). Optionally, a dissolution inhibitor can be added in an amount of up to about 20 weight % of the composition. A suitable dissolution inhibitor is t-butyl cholate (JN. Crivello et al., Chemically Amplified Electron-Beam Photoresists, Chem. Mater., 1996, 8, 376-381). Upon exposure to radiation, the radiation sensitive acid generator generates a strong acid. Suitable photoinitiators include triflates (e.g., triphenylsulfonium inflate), pyrogallol (e.g., trimesylate of pyrogallol); onium salts such as triarylsulfonium and diaryliodium hexafluoroantimonates, hexafluoroarsenates, trifluoromethanesulfonates; esters of hydroxyimides, -bis-sulfonyl- diazomethanes, sulfonate esters of nitro-substituted benzyl alcohols and napthoquinone-4-diazides. Other suitable photoacid initiators are disclosed in Reichmanis et al., Chem. Mater. 3, 395, (1991). Compositions containing triarylsulfonium or diaryliodonium salts are preferred because of their sensitivity to deep UV light (193 to 300 nm) and give very high resolution images. Most preferred are the unsubstituted and symmetrically or unsymmetrically substituted diaryliodium or triarylsulfonium salts. The photoacid initiator component comprises about 1 to 100 w/w % to polymer. The preferred concentration range is 5 to 50 w/w %. The photoresist compositions of the present invention optionally contain a sensitizer capable of sensitizing the photoacid initiator to longer wave lengths ranging from mid UV to visible light. Depending on the intended application, such sensitizers include polycyclic aromatics such as pyrene and perlene. The sensitization of photoacid initiators is well- known and is described in U.S. Patent Nos. 4,250,053; 4,371,605; and 4,491,628 which are all incorporated herein by reference. The invention is not limited to a specific class of sensitizer or photoacid initiator. The present invention also relates to a process for generating a positive tone resist image on a substrate comprising the steps of: (a) coating a substrate with a film comprising the positive tone resist composition of the present invention; (b) imagewise exposing the film to radiation; and (c) developing the image. The first step involves coating the substrate with a film comprising the positive tone resist composition dissolved in a suitable solvent. Suitable substrates are comprised of silicon, ceramics, polymer or the like. Suitable solvents include propylene glycol methyl ether acetate (PGMEA) cyclohexanone, butyrolactate, ethyl lactate, and the like. The film can be coated on the substrate using art known techniques such as spin or spray coating, or doctor blading. Preferably, before the film has been exposed to radiation, the film is heated to an elevated temperature of about 90°C to 150°C for a short period of time of about 1 min. In the second step of the process, the film is imagewise exposed to radiation suitably electron beam or electromagnetic preferably electromagnetic radiation such as ultraviolet or x-ray, preferably ultraviolet radiation suitably at a wave length of about 193 to 514 nm preferably about 193 nm to 248 nm. Suitable radiation sources include mercury, mercury/xenon, and xenon lamps, x-ray or e-beam. The radiation is absorbed by the radiation-sensitive acid generator to produce free acid in the exposed area. The free acid catalyzes the cleavage of the acid labile pendant group of the copolymer which converts the copolymer from dissolution inhibitor to dissolution enhancer thereby increasing the solubility of the exposed resist composition in an aqueous base. The exposed resist composition is readily soluble in aqueous base. This solubility is surprising and unexpected in light of the complex nature of the cycloaliphatic backbone and the high molecular weight of the norbornene monomer units bearing the carboxy lie acid functionality. Preferably, after the film has been exposed to radiation, the film is again heated to an elevated temperature of about 90°C to 150°C for a short period of time of about 1 minute. The third step involves development of the positive tone image with a suitable solvent. Suitable solvents include aqueous base preferably an aqueous base without metal ions such as tetramethyl ammonium hydroxide or choline. The composition of the present invention provides positive images with high contrast and straight walls. Uniquely, the dissolution property of the composition of the present invention can be varied by simply varying the composition of the copolymer. The present invention also relates to an integrated circuit assembly such as an integrated circuit chip, multichip module, or circuit board made by the process of the present invention. The integrated circuit assembly comprises a circuit formed on a substrate by the steps of: (a) coating a substrate with a film comprising the positive tone resist composition of the present invention; (b) imagewise exposing the film to radiation; (c) developing the image to expose the substrate; and (d) forming the circuit in the developed film on the substrate by art known techniques. After the substrate has been exposed, circuit patterns can be formed in the exposed areas by coating the substrate with a conductive material such as conductive metals by art known techniques such as evaporation, sputtering, plating, chemical vapor deposition, or laser induced deposition. The surface of the film can be milled to remove any excess conductive material. Dielectric materials may also be deposited by similar means during the process of making circuits. Inorganic ions such as boron, phosphorous, or arsenic can be implanted in the substrate in the process for making p or n doped circuit transistors. Other means for forming circuits are well known to those skilled in the art. The following examples are detailed descriptions of methods of preparation and use of certain compositions of the present invention. The detailed preparations fall within the scope of, and serve to exemplify, the more generally described methods of preparation set forth above. The examples are presented for illustrative purposes only, and are not intended as a restriction on the scope of the invention. Example 1 (Synthesis of Norbornene Itaconic Anhydride (bicyclo[2.2.1]helpt-5-ene- 2-spiro-3'-exo-succinic anhydride) To a 500 ml dried beaker was placed 100 grams (0.8482 mols) of itaconic anhydride and 300 ml of dried THF. The solution was cloudy therefore the solution was filtered through a 0.45μ filter. A clear colorless filtrate was obtained. Into a dried 500 ml three-neck flask equipped with a magnetic stirrer, nitrogen inlet, condenser, internal temperature monitor and addition funnel was placed the itaconic anhydride THF solution. To the itaconic anhydride solution was added via the additional funnel 90 grams (1.36 mols) of freshly prepared cyclopentadiene (CPD), the temperature of the reaction was controlled at 32-35°C by adjusting CPD addition speed and a water bath. After the addition was complete the reaction was allowed to stir at room temperature overnight. The reaction solution was placed on the rotovapor to remove the bulk of the THF, resulting in a solid. The solid product was crystallized from boiling hexane and dried at 30°C in a vacuum oven, yield = 86.5%. 1 t " The product was identified by H and C NMR and IR spectroscopy. Examples 2 to 16 A 250 ml glass reaction bottle and a 10 ml catalyst bottle were dried in an oven at 1 10°C for a minimum of 4 hours. Once dry, the glass bottle was purged with dry nitrogen gas until the vessel was cool. The following monomers, norbornene, itaconic anhydride, t-butyl ester norbornene, and methyl acetate norbornene were placed into the bottle in the mole % amounts indicated in the table below. 25.33g of toluene was also added to the reaction bottle. The vessel was crimp capped and allowed to stir until all of the itaconic norbornene monomer was in solution. The solution was purged for 20 to 30 minutes with dry nitrogen through an 18-gauge stainless steel needle. While the monomer solution was purging a dry 10 ml glass crimp neck bottle was taken into the inert atmosphere glove box along with a solvent syringe and crimp cap. 0.09173g (1.89E-03 mol) of the nickel catalyst (C 6 H 5 )Ni(C 6 F 5 ) 2 was weighed into the 10 ml bottle. Once the catalyst was weighed out, the vial was capped and 9.0 ml of dry toluene, already in the glove box, was added. The catalyst was added after purging the syringe with dry nitrogen and pressurizing the catalyst solution vial. About 5 minutes into the reaction the polymer solution began to exotherm (10-15°C). The viscosity also increased substantially. A nitrogen purge was placed on the vial to reduce the internal temperature and prevent over pressurizing. About 30 ml of dry toluene was added to the reaction mixture to reduce the viscosity. The reaction was allowed to continue for 5 hours. Once the reaction was complete, the polymer solution was diluted with dry tetrahydrofuran in a 1 : 1 volume ratio. Then, 50 ml of conditioned Amberlite IRC-718 resin was added. This was allowed to mix vigorously overnight (16 to 17 hours). The resin was removed through filtration. A course glass frit filter was used first to remove the large particles and then the polymer solution was filtered through a 0.22 micron Teflon membrane filter. The polymer was isolated by precipitating into a 2:1 volume ratio of hexanes to methyl tertiary butyl ether. Once all of the polymer solution had been precipitated, the polymer was stirred slowly in the non-solvent for 1 hour. The solid polymer was filtered through a medium glass frit. The polymer was put into a pre-weighed drying dish and placed into an evacuated oven at 60°C overnight (16 to 17 hours). C 13 NMR and IR spectroscopy was used to determine the polymer composition as indicated in the table below. Molecular weight was determined by GPC and residual monomer by GC.

The reaction mixture was purged with Argon for 10 minutes. To the reaction solution at room temperature was added via syringe the nickel catalyst solution in a monomer to catalyst ratio of 500/1. The catalyst solution was prepared inside the dry box by adding 0.0273 g (0.056 mmol) (CH 3 C 6 H 4 )Ni(C 6 F 5 ) 2 in 5 ml of toluene. The polymerization was allowed to stir for 6 hours after which the solution was diluted with tetrahydrofuran. The resulting polymer solution was treated first with preconditioned imidoacetic acid based Amberlite IRC-718 chelating resin, followed by Sulfonic acid based Amberlyst 15 ion exchange resin. The polymer solution was filtered, concentrated via rotary evaporation and precipitated into methanol The precipitated polymer was filtered and dried overnight under reduced pressure. The overall yield of polymer was 4.0g (80%). The polymer was further characterized using GPC, IR and NMR.
