Abstract
Abstract A heterofunctional macromer represented by the formula: ##STR1## in which R 1 is H or C 1 -C 4 alkyl; R 2 is a (poly) lactone or (poly) ether chain; X 1 is --COO--, --COOCH 2 CH 2 OCO--, --CONHCOO--, --COOCH 2 CH 2 NH--COO-- ##STR2## X 2 is --O--, --COO-- or --OCO--NH--R 3 --NHCOO--group; R 3 is C 1 -C 6 alkylene, aromatic or alicyclic group; A is --CH 2 --, --C(CH 3 ) 2 -- or ##STR3## and reactive polymers derived from said macromer.
