| abstract | 1,177,487. Condensation polymers. IMPERIAL CHEMICAL INDUSTRIES Ltd. 23 Nov., 1967 [12 Dec., 1966], No. 55602/66. Heading C3R. Polymers are obtained by condensing organic compounds having methyl or methylene groups directly linked to an atom forming part of an aromatic nucleus or to an atom joined to another atom by a double or triple bond, with organic dihalides wherein both halogen atoms are attached to aliphatic carbon atoms, in the presence of at least two moles of a base per mole of organic compound, hydrogen halide being eliminated in the condensation. The methyl or methylene group may be attached to a benzene ring or to a vinyl, nitrile, carbonyl or sulphonyl group. In examples polymers are obtained by condensing benzyl cyanide with bis-(p-chloromethylphenyl) ether, malononitrile with bis-(p-chloromethylphenyl) ether, ethyl cyanide with bis-(p-chloromethylphenyl) ether, fluorene with bis-(p-chloromethylphenyl) ether, methyl cyanide with bis-(p-chloromethylphenyl) ether, diethyl malonate with α,α<SP>1</SP>- dibromo-p-xylene, fluorene with α,α<SP>1</SP>-dichloro - xylene, acetone with bis-(p-chloromethylphenyl) ether, methyl ethyl ketone with bis-(p-chloromethylphenyl) ether, acetylacetone with bis- (p-chloromethylphenyl) ether, diethyl malonate with bis-(p-chloromethylphenyl) ether, phenyl p-tolyl sulphone with bis (p-chloromethylphenyl) ether, o- and p-tolunitrile with bis-(pchloromethylphenyl) ether, nitromethane with bis-(p-chloromethylphenyl) ether, bis-(n-butylsulphonyl) methane with bis-(p-chloromethylphenyl) ether, N,N-dimethyltoluene-p-sulphonamide with bis-(p-chloromethylphenyl) ether, p-nitrotoluene with bis-(p-chloromethylphenyl) ether, benzyl cyanide with 2,5-dimethoxy-α,α<SP>1</SP>- dichloro-p-xylene, benzyl cyanide with α,α<SP>1</SP>- dichloro.p-xylene, benzyl cyanide with 2,5- dichloro - 3,6 - dimethyl - α,α<SP>1</SP> - dichloro - p - xylene, benzyl cyanide with 4,6-dimethyl- α,α<SP>1</SP>-dichloro-m-xylene, benzyl cyanide with 2-nitro-α,α<SP>1</SP>-dichloro-p-xylene, benzyl cyanide with 2,4,6 - trimethyl - α,α<SP>1</SP> - dichloro - m - xylene, benzyl cyanide with l,2-bis-(p-chloromethylphenoxy) ethane, cyclopentadiene with bis-(p-chloromethylphenyl) ether and malonitrile with 1,3-dibromopropane. |
