Abstract

Polymers of ethylenically unsaturated monomers are produced by (a) polymerizing said monomer in the presence of an anionic polymerization catalyst and an inert liquid medium to a predetermined average molecular weight and then (b) adding to the resulting polymerization system an organic compound containing at least one halogen atom and at least one ethylenically unsaturated group or a plurality of non-conjugated ethylenically unsaturated groups. In stage (b) the organic compounds containing at least one halogen atom and at least one ethylenically unsaturated group may have the general formula (Y)n-R-(X)m, in which R is a hydrocarbon group having 1 to 20 carbon atoms, X is a halogen atom, Y is an ethylenically unsaturated group in which the ethylenically unsaturated linkage is in the terminal position and "m" and "n" are each integers of at least 1. Examples given are the nuclear substituted halostyrenes, the nuclear substituted haloalkyl styrenes, halogenated poly-ethylenically unsaturated compounds such as 1-chloro-3,5-divinyl benzene, halogenated a -olefines and polyolefines such as 3-chloropropene-1 and chloroprene, and vinyl benzyl halides. The organic compounds containing a plurality of non - conjugated ethylenically unsaturated groups may have the general formula R-(X)n in which R and X are as above and "n" is an integer which is at least 2. Examples given are aromatic polyvinyl compounds such as the divinyl and trivinyl benzenes and the diallyl and triallyl benzenes, aliphatic non-conjugated polyolefines such as pentadiene-1,4 and polyethylenically unsaturated esters such as ethylene glycol dimethacrylate. The ethylenically unsaturated monomers, the anionic initiators and the liquid solvents may be styrene or alkyl or alkoxy substituted styrenes, conjugated diolefines, or acrylic or methacrylic esters; alkali metals and alkyl and aryl compounds thereof; and hydrocarbons, ethers and amides. In the examples stage (a) is carried out by polymerizing separately butadiene, styrene and methyl methacrylate using butyl lithium or sodium naphthalene as catalyst.
