Heading C3G. 5 to 95% by weight of isobutylene is grafted on to 95 to 5% of a diene polymer with a molecular weight of 1500 to 5,000,000 which contains 1 to 0À000001 halogen atom per monomer unit in the presence of 0À000001 to 5%, based on the total weight of isobutylene and diene polymer, of a Lewis acid at -150‹ to -30‹ C. at a pressure of 1 to 10 atmospheres. The diene polymer may be a homo- or copolymer into which halogen is introduced after polymerization or during polymerization, in the latter case by use of a halogen-containing monomer, e.g. chloroprene, a chloropropene or allyl chloride. The diene, polymer and isobutylono may be dissolved in a solvent prior to reaction. In the examples, the diene polymers used are polybutadienes, which may be oils, containing a small percentage of Br 2 , C1 2 or I 2 ; a butadiene/2-chloropropene copolymer; an isoprene/2 - chloropropone copolymer - polychloroprene; a chlorinated butadiene/styrene copolymer; a brominated or chlorinated butadiene/α-methyl styrene copolymer or a chlorinated butadiene/α-methyl styrene block copolymer. The catalysts employed are TiCl 4 , SnCl 4 , VBr 4 , MoCl 5 , VOCl 3 , GaCl 3 , GaBr 3 , VCl 4 , NbCl 5 , AlCl 3 , BF 3 , SbCl 5 , FeCl 3 , TaCl 5 , MoCl 5 (C 2 H 5 ) 2 - AlCl, AlBr 3 and (C 2 H 5 ) 3 Al. The solvents used are toluene, liquid ethylene and n-hexane. The graft polymers may be vulcanized.

    Abstract: 1,138,299. Stereoblock butadiene polymers. BADISCHE ANILIN- & SODA-FABRIK A.G. 3 May, 1966 [4 May, 1965], No. 19366/66. Heading C3P. Stereoblock polymers are made by polymerizing butadiene with a Ziegler-Natta type catalyst comprising an alkyl metal compound and a compound of a transition metal of Groups IV to VIII, and whilst unreacted butadiene is still present in the polymerization mixture adding a catalyst of the same type but which converts butadiene into a polymer whose configuration is different to the configuration of the polybutadiene first prepared, and continuing the polymerization. In examples, effected in solvents, the following catalysts are used: (1) (C 2 H 5 ) 3 Al, AlBr 3 , and TiI 4 , followed by (C 2 H 5 ) 3 Al and VCl 3 , (2) as (1) but VCl 3 replaced by VCl 4 , (3) (C 4 H 9 ) 3 Al and TiCl 3 , followed by (C 2 H 5 ) 2 AlI and TiCl 3 , (4) (C 4 H 9 ) 2 AlCl and TiCl 3 , followed by (C 2 H 5 ) 2 AlI and TiCl 3 , (5) (C 2 H 5 ) 3 Al and TiCl 4 , followed by (C 2 H 5 ) 2 AlI and TiCl 3 , (6) (C 4 H 9 ) 3 Al and Ti(-OC 4 H 9 ) 4 , followed by (C 2 H 5 ) 3 Al and VCl 3 , (7) Cr triacetylacetonate and (C 4 H 9 ) 3 Al followed by (C 4 H 9 ) 3 Al, (8) Sn(C 4 H 9 ) 4 and ZrCl 4 , followed by amyl Na and TiCl 3 . The polymers may be sulphur vulcanized.

A 1,3-diene or a monomer mixture containing a 1,3-diene is polymerized in aqueous emulsion using a redox catalyst of at least two components, wherein each component of the catalyst system is soluble in the monomer or monomer mixture to an amount of at least 1 % under polymerization conditions, one of the components comprising a butadiene sulphone. Suitable peroxides include cumene hydroperoxide, pinene hydroperoxide, benzoyl peroxide, p, p 1 -dinitrobenzoyl peroxide, lauroyl peroxide, diethyl-, ditertiary butyl- and ditolyl peroxycarbonate, ethyl α-methoxy peroxyacetate, 3 - phenyl - 3 - tert. - butyl peroxyphthalide, and γ-tertiary butyl peroxyvalerolactone.

    Abstract: Vulcanizable polyethers are prepared by reacting an epoxy compound of the general formula or in which R is H or CH3 and n is 1 to 3, in the presence of a halogen-containing Friedel-Crafts compound of a Group IIIa, IVa or IVb element and/or an alkyl derivative of a metal of the said Groups, and at temperatures of -50 DEG to +150 DEG C. The process may be carried out in the presence of inert diluents and a minor amount of the corresponding saturated epoxide may also be present. A temperature of -10 DEG to 50 DEG C. is preferred. Suitable catalysts include titanium (IV) chloride, tin (IV) chloride' aluminium chloride, triethyl aluminium, tetrabutyl titanium, and zirconium oxychloride. The examples describe the polymerization of butenediol monoglycidyl ether, hexynediol monoglycidyl ether, octenediol monoglycidyl ether and a mixture of hexenediol monoglycidyl ether and octynediol monoglycidyl ether, the products being vulcanized with conventional agents.ALSO:The compounds and are prepared by reacting the corresponding olefinically or acetylenically unsaturated diols with epichlorohydrin in the molar ratio of 1:1 at temperatures between about -10 DEG and +10 DEG C., with boron trifluoride dietherate, and then converting the products into the corresponding epoxy compounds by eliminating hydrogen chloride with sodium ethorate. The process is exemplified using but-2-ene-1,4-diol and epichlorohydrin to give 1-(1-chloro-2-hydroxypropoxy) - but - 2 - ene - 4 - ol and, on elimination of hydrogen chloride, but-2-ene-1,4-diol monoglycidyl ether. Hexenediol, octenediol, butynediol, hexynediol and octynediol are also mentioned as reactants with the epichlorohydrin.
