Title: Block copolymer dispersions
IPC: C08F297/02
Filed: 1972-08-08
Abstract: 1412584 Block copolymer dispersion polymerization IMPERIAL CHEMICAL INDUSTRIES Ltd 23 Oct 1972 [1 Nov 1971 8 Aug 1972] 50639/71 and 36937/72 Heading C3P A dispersion of a block copolymer in a diluent, the copolymer comprising at least one block (C) insoluble in the dileunt and forming at least part of the core of the dispersed particles and at least one terminal thermoplastic block (A) which is saturated by the diluent, is obtained by sequential polymerization in the appropriate diluent using a monofunctional anionic initiator to form the soluble block initially and finally the insoluble block. Preferred polymers, comprising three blocks, have the structure ABC where B is an elastomeric block, which may be soluble in the diluent. The insoluble C blocks may be cross-linked. Preferred procedures involve the presence during the final stage of the polymerization, during which the insoluble block is formed, of (a) a " living " polymer containing at least a terminal thermoplastic block soluble in said diluent, (b) a block copolymer of a soluble block and of an insoluble block containing at least one polymerizable group, or (c) a copolymer incapable of initiating polymerization and comprising at least one soluble and at least one insoluble block. The particles of the dispersion may be recovered by addition of a precipitant and fabricated into articles, such as sheets. In the examples, the following combinations of monomers are polymerized in nheptane using sec-butyl lithium:- t-butylstyrene - b - styrene, t - butylstyrene - b - isoprene - b - styrene, t - butylstyrene - b - isoprene - b - styrene - co - divinylbenzene, tbutylstyrene - b - styrene - co - divinylbenzene, t - butylstyrene - b - methyl methacrylate, t - butylstyrene - b - styrene - b - acrylonitrile, and t - butylstyrene - b - styrene - co - isoprene. The latter block in the last copolymer is crosslinked with S 2 Cl 2 . In some cases tetrahydrofuran is present in the final stage of polymerization. Additive polymers present in some cases are t - butylstyrene - b - styrene (" living " lithium terminal), t-butylsturene-b-styrene-codivinyl benzene (terminated in air), and tbutylstyrene-b-styrene (terminated in air). In these examples the t-butyl styrene polymer is the soluble block. Alternative combinations mentioned include styrene (soluble)-b-elastomerb - methyl methyacrylate, dimethylamino ethyl methacrylate or methacrylonitrile in cyclohexane and styrene (soluble)-b-elastomer-bmethyl methacrylate or dimethylaminoethyl methacrylate in benzene or toluene.

Title: Ornithine derivatives and their use in the preparation of peptides
IPC: C07K7/16
Filed: 1964-09-12
Abstract: Novel Nd  - phthalyl - L - orinthine derivatives of the formula <FORM:1089771/C2/1> wherein R and R1 represent hydrogen, halogen, C1- 7 alkyl, nitro or C1- 7 alkoxy, Y represents hydrogen, an alkali metal or a group capable of protecting the acid radical or of activating the said radical in peptide synthesis and Z represents hydrogen or a group capable of protecting the amino radical in peptide synthesis, and acid addition salts of such compounds, are prepared by reacting ornithine with a copper salt, treating the resulting ornithine copper complex with a compound of the formula <FORM:1089771/C2/2> wherein the lower alkyl radical contains one to seven carbon atoms, and treating the resulting phthalyl-ornithine copper complex with water, H2S or an acid to destroy said complex. The above Nd  - phthalyl - L - ornithine derivatives may be reacted with a peptide or an amino acid or an ester thereof in a liquid phase in the presence of an excess of an organic base followed by acidification of the reaction mixture to yield a corresponding Nd  - (substituted or unsubstituted) - phthalyl - ornithine - containing peptide. This latter class of compounds may be reacted with at least one further amino acid, peptide or ester thereof to obtain corresponding higher Nd  - (substituted or unsubstituted) - phthalyl-ornithine containing peptides.  Dephthalylation, e.g. by treatment with hydrazine, may be carried out after any peptide formation step to yield the corresponding (Nd -unsubstituted ornithine)-containing peptides.  The latter compounds may be further guanylated, e.g. by treatment with 1 - guanyl - 3,5 - dimethylpyrazole, to yield corresponding arginine - containing peptides. Using the above procedures, dephthalylation to give S - benzyl - N - benzyloxycarbonyl - L - cysteinyl - L - tyrosyl - L - phenylalanyl - L - glutaminyl - L - asparaginyl - S - benzyl - L - cysteinyl - L - propyl - L -ornithyl - glycinamide may be followed by reduction with an alkali metal and liquid ammonia and subsequent oxidation to yield 8-L-ornithine vasopressin. Insertion of a guanylation step prior to the reduction step gives after oxidation 8-L-arginine vasopressin.  8 - L - ornithine vasotocin and 8-L-arginine vasotocin are obtained similarly from S - benzyl - N - benzylcxycarbonyl - L-cysteinyl - L - tyrosyl - L - isoleucyl - L - glutaminyl - L - asparagynyl - S - benzyl - L - cysteinyl - L - prolyl - L - ornithyl - glycinamide. Tertiary - butyl Na  - benzyloxycarbonyl - L - tryptophylglycinate is prepared by reacting benzyloxycarbonyl - L - tryptophane nitrophenyl ester with glycine tertiary-butyl ester. Tertiary - butyl - L - tryptophylglycinate is prepared by hydrogenation of the corresponding Na -benzyloxy compound.  This product may be isolated as the oxalate.

Abstract: 987,711. Feeding sheets. BRADFORD SPEED PACKAGING & DEVELOPMENT CORPORATION. Oct. 9, 1962 [Oct. 9, 1961], No. 38286/62. Heading B6B. A device for feeding individual box blanks or the like to a boxfolding machine comprises a suction separator 23 movable through a work stroke between a pick-up station and a delivery station and connected to a source of suction through a line 28, a control valve 29 in said line for applying and disconnecting the source of suction at the respective ends of the work stroke, a vent valve 37 in said line operable independently of the control valve for relieving the suction at the separator head in response to a no-demand signal, said vent valve being positioned so as to be operable only at a point within the return movement to the pick-up station, and means for locking said vent valve in its operated or non-operated position during the movement from said point until after the separator head has departed from the pick-up station on its way towards the delivery station. The vent valve is carried by an arm 19 supporting the separator and comprises a body 39 having a bore 40 into and from which the suction line 28 extends at ports 41, 42. Normally a vent port 43 is closed by a member 44 on a spring-loaded arm 45 pivoted at 46. The arm is provided with a cam surface 48. Means such as photo-electric cells are provided to detect an accumulation or jamming of boxes in the delivery line of the machine and consequently energize a solenoid 49 having an armature 50 connected to a lever 52. The latter is pivoted on energization of the solenoid to position a roller 53 in the path of the cam surface 48 as the separator approaches the stack, whereby the valve 37 is opened to render the separator ineffective. If the solenoid is energized after the separator has approached the stack, the roller 53 is lifted and engages the underside of the cam surface 48. In this case, the valve remains closed and separation takes place. Conversely, if the solenoid is de-energized after the valve has been opened, the spring 51 tends to move the lever 52 in a clockwise direction, as seen in Fig. 3, whereby the valve is retained opened. Thus, partial withdrawal or misfeeding of a box blank is prevented. The separator 23 is mounted on the arm 19 through bellows 24.
