| abstract | 1432783 Introducing polymerizable end groups into polymers CPC INTERNATIONAL Inc 26 March 1973 [14 April 1972 21 Aug 1972] 34683/75 Divided out of 1432782 Addition to 1392612 Headings C3P and C3R A process for preparing a copolymerizable macromolecular monomer comprises polymerizing at least one anionically polymerizable monomer in the presence of an anionic polymerization initiator to thereby form a monofunctional living polymer; optionally, reacting the monofunctional living polymer with a capping agent; thereafter, reacting the monfunctional living polymer with a terminating agent which contains a copolymerizable end group; and recovering said copolymerizable macromolecular monomer; characterized in that (a) said copolymerizable macromolecular monomers have a substantially uniform molecular weight distribution such that the ration of Mw/Mn is less than 1À1, wherein Mw is the weight average molecular weight of the macromolecular monomers, and Mn is the number average molecular weight of the macromolecular monomers, and (b) said macromolecular monomer contains at least one member selected from the group consisting of: (i) a residue of an alkali metal salt of a tertiary alcohol anionic polymerization initiator; (ii) a capping agent selected from butadiene or isoprene; (iii) a copolymerizable end group derived from a terminating agent selected from 2-halomethyl 1,3-butadiene, haloalkylmaleic anhydride, haloalkylmaleate esters, vinyl haloaryls, vinyl haloalkaryls, maleic anhydride, acrylic anhydride methacrylic anhydride, and an epihalohydrin the epoxy group of which is hydrolysed and then reacted with acrylyl halide, methacrylyl halide or maleic acid halide; (iv) a polymeric segment of a vinyl aromatic hydrocarbon having a molecular weight in the range of from 5000 to 50,000 and a polymeric segment of a conjugated diene containing 4 to 12 carbon atoms per molecule. The products may be represented by the formula I-(P 1 ) n -(X) w -(Y) in which I is the residue of a monofunctional anionic initiator, P 1 is an anionically polymerized monomer, X is derived from a capping agent and Y is derived from a terminating agent containing a polymerizable group, n is at least 20 and w is zero or 1. In examples polyethylene oxide obtained using sec. butyl lithium initiator is terminated with vinyl benzyl chloride, and polymers of vinyl pyridine, methacrylontrile, methyl methacrylate, dimethylacrylamide, styrene, isoprene, or polystyrene-polyisoprene block copolymers obtained using as initiators potassium t-butyl alkoxylate, n-butyl lithium, t-butyl lithium, or sec. butyl lithium, are terminated with allyl chloride, vinyl benzyl chloride, maleic anhydride, or methacrylyl chloride optionally after an intermediate capping reaction with butadiene or ethylene oxide. |
