Abstract

1448516 Vinyl-terminated prepolymers, and polymerizable compositions thereof KAO SOAP CO Ltd 7 Aug 1974 [14 Aug 1973] 34794/74 Headings C3P and C3R Vinyl-terminated prepolymers are obtained by reacting (a) an organic polyisocyanate with (b) at least one equivalent of a compound of formula wherein R is -CH 2 - or n is an integer of 1-4, and X is -H or -CH 3 . Component (a) may itself be a prepolymer. The above reaction suitably takes place in solution in a polymerizable monomer with which the vinylterminated product may be copolymerized, and the invention includes the polymerizable compositions so formed. Examples are given as follows: (1) mixed 2,4/2,6-tolylene diisocyanates are reacted with a polyester glycol (prepared from propylene glycol and isophthalic acid) in solution in p-chlorostyrene to form a polisocyanate reactant (a), which is then reacted with (b) p-(2-hydroxypropyl) styrene; (2) 2,4- tolylene diisocyanate is reacted in styrene solution with polyoxypropylene-modified Bisphenol A to form reactant (a), which is then reacted with (b) p-vinyl-benzyl alcohol; (4) 4,4<SP>1</SP>-diphenylmethane diisocyanate is reacted in methyl methacrylate solution with polyoxytetramethylene glycol to form reactant (a), which is then reacted with (b) ethylene glycol-mono/-(p-vinylphenyl) ethyl ether; and (5) 1,3-phenylene diisocyanate is reacted in styrene solution with liquid polybutadiene glycol to form reactant (a), which is then reacted with (b) p-hydroxyethyl styrene. The polymerizable compositions thus obtained are cured at room temperature in the presence of cobalt naphthenate and methyl ethyl ketone peroxide, and are then post-cured at 100‹ C. In Example 3, the polymerizable compositions of Examples 1 and 2 are cured in the presence of 3 sheets of chopped strand glass mat to form a fibre-reinforced plastic.
