Title: Improvements in or relating to a process for preparing modified crystalline propylene polymers
IPC: C08F255/02
Filed: 1966-06-16
Abstract: Modified crystalline propylene polymers are prepared by reacting maleic anhydride with a particulate crystalline propylene polymer while agitating in an inert atmosphere at a temperature from 80 DEG to 10 DEG  C. below the melting point of the polymer in the presence of an organic peroxygen compound and in the absence of a solvent for the polymer for such a time as to cause chemical reaction of the polymer with 0.1 to 10% of maleic anhydride, based on the weight of polymer.  The polymer may be a crystalline polypropylene or a crystalline polymer of propylene with another olefin, e.g. ethylene or butene-1.

Title: Compositions containing halogen-containing polyesters
Inventor: PRILL ERHARD JOHN
IPC: C08G63/682
Filed: 1964-07-01
Abstract: Polyesters are made by reacting a polyhydric alcohol with a dicarboxylic acid compound of formula <FORM:1079015/C3/1> in which X and X1 are halogen atoms, R and R1 are hydrogen atoms or alkyl groups and Z and Z1 are carboxylic acid groups or esterifiable functional derivatives thereof or Z and Z1 together form an anhydride group. The polyhydric alcohol may be an alkylene glycol, an oxyalkylene glycol, a glycerol mono-ether or -ester, a pentaerythritol mono- or di-ether or -ester, a butyne- or butene-diol, a glycerol allyl or vinyl ether or a pentaerythritol mono- or di-allyl or -vinyl ether. Copolymerizable polyesters are made by including an unsaturated polycarboxylic compound in the reaction mixture (e.g. maleic, itaconic, fumaric, citraconic, mesaconic, tetrahydrophthalic or endomethylene tetrahydrophthalic acids or their ester-forming derivatives).  The reaction mixture may also include (a) phthalic, isophthalic, hexa-hydrophthalic, succinic or adipic acid; (b) acetic, propionic, butyric, valeric or benzoic acid; (c) butyl, hexyl, octyl, dodecyl, benzyl or tetrahydrofurfuryl alcohol.  Those polyesters containing ethylenic unsaturation may be copolymerized with unsaturated monomers, e.g. styrene, vinyl toluene, diallyl phthalate, methyl methacrylate or triallyl cyanurate.  Suitable polymerization catalysts are peroxides, hydroperoxides, per salts, per esters and azo compounds.  These polyesters may be used in the manufacture of fire-resistant laminates.ALSO:The Specification discloses 3,6-endomethylene - 4,5 - dihalocyclohexane - 1,2 - dicarboxylic acid compounds of formula <FORM:1079015/C2/1> in which X and X1 are halogen atoms, R and R1 are hydrogen atoms or alkyl groups, Z and Z1 are carboxylic acid groups or esterifiable functional derivatives thereof (e.g. alkoxycarbonyl or carboxylic halide groups) or Z and Z1 together form an anhydride group.  The compounds may be prepared (a) by the addition of halogen to the corresponding ethylenically unsaturated compound, addition of bromine being effected at - 25 DEG C. to 50 DEG  C. and in the presence of a solvent (and possibly in the presence of artificial light or sunlight) and addition of chlorine being effected at - 50 DEG  C. to 25 DEG  C. or (b) using sulphuryl chloride or phosphorous pentachloride as halogenating agents.  A bromochloride may be prepared by treating a dichloride with sodium bromide in acetone or by using a mixture of chlorine and bromine.  An example describes the preparation of 3,6-endomethylene - 4,5 - dibromocyclohexane dicarboxylic acid anhydride by brominating 3,6-endomethylene - 1,2,3,6 - tetrahydrophthalic anhydride in the presence of chloroform.

Filed: 1928-09-24
Abstract: 323,257. West, E., and West's Gas Improvement Co., Ltd. Sept. 24, 1928. Tipping-apparatus.-Relates to apparatus of the type in which the wagon n is carried upon a platform k pivoted at m upon a frame a which on turning brings clamping means into operation. The frame a is pivotally supported at e on arms b which turn about a fixed axis c. Top clamping arms f pivoted at g upon the arms b are con. nected with the frame a by links h. When the frame a is turned in the direction of the arrow q, it rotates first about the pivots e causing the arms f to move downwards until the bar f<1> engages the wagon, and owing to the reaction of the clamping bar the further rotation of the frame a takes place about the fixed axis c. In the inverted position the weight of the various parts keeps the wagon held against the platform k. The frame may be rotated by ropes connected to the ends t, and returns by gravity. A ballast box is provided at s. During the first movement of the frame a, the weight of the wagon keeps the arms b 'stationary with stops p bearing against the framework d.
