PCT No. PCT/EP94/03848 Sec. 371 Date Jun. 28, 1996 Sec. 102(e) Date Jun. 28, 1996 PCT Filed Nov. 22, 1994 PCT Pub. No. WO95/14725 PCT Pub. Date Jun. 1, 1995The invention pertains to a composition containing an activator system for free-radical polymerizations and a free-radical polymerizable compound of the general formula II:[H2C=CR1-C(=O)-O-R2-O-C(=O)-NH-Q-NH-C(=O)]2[{-O-R4a-O-C(=O)-NH-Q'-NH-C(=O)}m-O-R4a-O-](II)wherein m is from 0 to 10; R1 is hydrogen or a methyl group; R2 is a linear or branched chain alkyl group containing from 2 to 6 carbon atoms or an alkylene oxide containing from 4 to 21 carbon atoms; Q and Q' independently are aromatic, aliphatic or cycloaliphatic groups containing from 6 to 18 carbon atoms which are derived from the basic diisocyanate or diisocyanate mixtures; and R4a is derived from a polyesterdiol having a C:O ratio of >2.6, a C:H ratio of <10, and a molecular weight of from 1000 to 20,000. The invention further pertains to a process for the preparation of such composition and the use thereof.
