Claim 1
Independent Claim
58 words
A plasticized composition comprising (a) a linear, alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon of from 2 to 20 carbon atoms inclusive, and intimately mixed therewith, (b) from about 5% by weight to about 50% by weight based on total composition of an alkylene carbonate of from 3 to 23 carbon atoms inclusive.
Claim 2
Dependent Claim
58 words
A plasticized composition comprising (a) a linear, alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon of from 2 to 20 carbon atoms inclusive, and intimately mixed therewith, (b) from about 5% by weight to about 50% by weight based on total composition of an alkylene carbonate of from 3 to 23 carbon atoms inclusive.
Claim 3
Dependent Claim
45 words
The composition of claim 1 wherein the polymer is of the formula ##STR2## wherein B is a moiety of an ethylenically unsaturated hydrocarbon of at least 3 carbon atoms polymerized through the ethylenic unsaturation and the ratio of y:x is no more than about 0.5.
