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