ABSTRACT:
This invention relates to alkenyl ether polycarbonates having the formula ##STR1## wherein A is selected from the group consisting of lower alkyl and R'HC.dbd.CHOR--, R and R" are each independently a divalent radical having from 2 to 20 carbon atoms and are selected from the group of alkylene, mono- or poly- alkoxylated alkylene, alkenylene, alkynylene, arylene, alkarylene and aralkylene radicals, which radicals are optionally substituted with halo, alkyl, cyano, nitro or alkoxy; R' is hydrogen or lower alkyl; (n) has a value of from 1 to 10 and (m) has a value of from 0 to 10; with the proviso that R" contains at least 3 carbon atoms when m is zero. The invention also concerns the preparation and use of said alkenyl ether polycarbonates.
