Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
62 words
A composition comprising a grafted olefin/carbon monoxide copolymer comprising a substrate phase of a copolymer of a C 2-8 olefin and carbon monoxide containing from 0.1 to 40 percent by weight carbon monoxide having grafted thereto a graft polymer phase comprising one or more vinyl or vinylidene monomers, the weight ratio of substrate to graft polymer phase being from 0.1/100 to 100/0.1.
Claim 2
Dependent Claim
62 words
A composition comprising a grafted olefin/carbon monoxide copolymer comprising a substrate phase of a copolymer of a C 2-8 olefin and carbon monoxide containing from 0.1 to 40 percent by weight carbon monoxide having grafted thereto a graft polymer phase comprising one or more vinyl or vinylidene monomers, the weight ratio of substrate to graft polymer phase being from 0.1/100 to 100/0.1.
Claim 3
Dependent Claim
17 words
A composition according to claim 1 wherein the olefin/carbon monoxide copolymer substrate is an ethylene/carbon monoxide copolymer.
Claim 4
Dependent Claim
24 words
A composition according to claim 2 wherein the carbon monoxide content of the olefin/carbon monoxide copolymer substrate is from 0.5 to 10 weight percent.
Claim 5
Dependent Claim
17 words
A composition according to claim 1 wherein the graft to substrate ratio is from 1:100 to 100:1.
Claim 6
Dependent Claim
21 words
A composition according to claim 1 wherein the graft polymer comprises a polymer of methyl methacrylate, styrene, acrylonitrile, or mixtures thereof.
Claim 7
Dependent Claim
23 words
A composition according to claim 1 prepared by contacting the substrate copolymer with the monomers and initiating free radical polymerization of the mixture.
