Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
47 words
A thermoplastic composition comprising a blend of about 20 to 98 parts by weight of at least 10% partially neutralized acid containing acrylic-olefin copolymer rubber, and about 80 to 2 parts by weight of polyvinylchloride (PVC) per 100 parts by weight of said rubber and PVC combined.
Claim 2
Dependent Claim
47 words
A thermoplastic composition comprising a blend of about 20 to 98 parts by weight of at least 10% partially neutralized acid containing acrylic-olefin copolymer rubber, and about 80 to 2 parts by weight of polyvinylchloride (PVC) per 100 parts by weight of said rubber and PVC combined.
Claim 3
Dependent Claim
45 words
The composition of claim 1 in which the acrylic copolymer rubber is a polymer, of ethylene and 25 mole percent or more of a mixture of acrylic or methacrylate acid and acrylic ester, and is at least 50 to 100 percent neutralized with metal ion.
Claim 4
Dependent Claim
39 words
The composition of claim 2 in which the rubber is a polymer of at least 50 mole percent of ethylene, about 0.5 to 10 mole percent of acrylic acid, and about 15 to 49.5 mole percent of alkyl acrylate.
Claim 5
Dependent Claim
12 words
The composition of claim 3 in which the PVC is a homopolymer.
Claim 6
Dependent Claim
67 words
An elastoplastic composition comprising a blend of neutralized acid containing acrylic-olefin copolymer rubber, in an amount sufficient to impart rubberlike elasticity up to 98 weight percent of the composition,, and PVC, in an amount up to 50 weight percent of the composition, with the proviso that when the amount of PVC exceeds the amount of rubber, sufficient plasticizer is present to impart rubberlike elasticity to the composition.
Claim 7
Dependent Claim
67 words
An elastoplastic composition comprising a blend of neutralized acid containing acrylic-olefin copolymer rubber, in an amount sufficient to impart rubberlike elasticity up to 98 weight percent of the composition,, and PVC, in an amount up to 50 weight percent of the composition, with the proviso that when the amount of PVC exceeds the amount of rubber, sufficient plasticizer is present to impart rubberlike elasticity to the composition.
Claim 8
Dependent Claim
41 words
The composition of claim 5 comprising 98 to 50 parts by weight of metal ion neutralized acid containing acrylic copolymer rubber and 2 to 50 parts by weight of PVC per 100 parts by weight of said rubber and PVC combined.
Claim 9
Dependent Claim
36 words
The composition of claim 6 comprising metal ion neutralized acid containing acrylic copolymer rubber and about 10 to 40 parts by weight percent of PVC per 100 parts by weight of said rubber and PVC combined.
Claim 10
Dependent Claim
30 words
The composition of claim 7 in which the rubber is a polymer of ethylene, and 25 mole percent or more of a mixture of alkyl acrylate and unsaturated carboxylic acid.
Claim 11
Dependent Claim
37 words
The composition of claim 8 in which the rubber comprises at least 50 mole percent of ethylene, about 0.5 to 10 mole percent of acrylic or methacrylic acid, and 15 to 49.5 mole percent of alkyl acrylate.
Claim 12
Dependent Claim
12 words
The composition of claim 9 in which the PVC is a homopolymer.
Claim 13
Dependent Claim
16 words
The composition of claim 9 in which the source of metal ion is a metal oxide.
Claim 14
Dependent Claim
17 words
The composition of claim 11 in which the rubber is neutralized with magnesium ion or calcium ion.
Claim 15
Dependent Claim
37 words
The composition of claim 12 comprising a copolymer rubber containing about 1 to 5 weight percent of acrylic acid and about 0.5 to 5 parts by weight of metal oxide per 100 parts by weight of rubber.
