Patent ID: 7288613

Claim:
A polymerizable composition, comprising a) at least one ethylenically unsaturated monomer or oligomer selected from the group consisting of ethylene, propylene, n-butylene, i-butylene, styrene, substituted styrene, conjugated dienes, acrolein, vinyl acetate, vinylpyrrolidone, vinylimidazole, maleic anhydride, (alkyl)acrylic acidanhydrides, (alkyl)acrylic acid salts, (alkyl)acrylic esters, (meth)acrylonitriles, (alkyl)acrylamides, vinyl halides and vinylidene halides and b) a compound of formula Ia, IIa or IIIa wherein X is CH 3 CH-phenyl; n is 1 Y and Y′ are independently C 1 -C 12 alkyl, C 3 -C 12 alkenyl, phenyl or benzyl; or Y and Y′ together form one of the bivalent groups —C(R 1 )(R 2 )—CH(R 3 )—, CH(R 1 )—CH 2 —C(R 2 )(R 3 )—, —CH(R 2 )—CH 2 —C(R 1 )(R 3 )— or —CH 2 —C(R 1 )(R 2 )—CH(R 3 )— wherein R 1 is hydrogen, C 1 -C 12 alkyl, COO—(C 1 -C 12 )alkyl or CH 2 OR 4 ; R 2 and R 3 are independently hydrogen, methyl, ethyl, or COO—(C 1 -C 12 )alkyl; and R 4 is hydrogen, C 1 -C 12 alkyl, benzyl, or a monovalent acyl residue derived from an aliphatic, cycloaliphatic or aromatic monocarboxylic acid having up to 12 carbon atoms.
