Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
60 words
An impact-resistant resin composition comprising an intimate mixture of from 1 to 30 parts by weight of an essential oil and 100 parts by weight of a resin resulting from the polymerization of a major proportion of an unsaturated nitrile in the presence of a preformed rubber component and optionally a minor proportion of at least one other polymerizable component.
Claim 2
Dependent Claim
60 words
An impact-resistant resin composition comprising an intimate mixture of from 1 to 30 parts by weight of an essential oil and 100 parts by weight of a resin resulting from the polymerization of a major proportion of an unsaturated nitrile in the presence of a preformed rubber component and optionally a minor proportion of at least one other polymerizable component.
Claim 3
Dependent Claim
204 words
The composition of claim 1 wherein the resin is one which results from the polymerization of 100 parts by weight of A. at least 50% by weight of at least one nitrile having the structure ##STR7## wherein R is hydrogen, a lower alkyl group having from 1 to 4 carbon atoms, or a halogen, and B. up to 50% by weight based on the combined weights of (A) and (B) of an ester having the structure ##STR8## wherein R 1 is hydrogen, an alkyl group having from 1 to 4 carbon atoms, or a halogen, and R 2 is an alkyl group having from 1 to 6 carbon atoms in the presence of from 1 to 40 parts by weight of C. a rubbery polymer of a conjugated diene monomer selected from the group consisting of butadiene and isoprene and optionally a comonomer selected from the group consisting of styrene, a nitrile monomer having the structure ##STR9## wherein R has the foregoing designation and a monomer having the structure ##STR10## wherein R 1 and R 2 have the foregoing respective designations, said rubbery polymer containing from 50 to 100% by weight of polymerized conjugated diene and from 0 to 50% by weight of comonomer.
Claim 4
Dependent Claim
9 words
The composition of claim 2 wherein (A) is acrylonitrile.
Claim 5
Dependent Claim
11 words

Claim 8
Dependent Claim
10 words
The composition of claim 3 wherein the oil is veratrole.
Claim 9
Dependent Claim
11 words
The composition of claim 3 wherein the oil is cinnamyl alcohol.
Claim 10
Dependent Claim
10 words
The composition of claim 3 wherein the oil is iso-safrol.
Claim 11
Dependent Claim
10 words
The composition of claim 3 wherein the oil is cineole.
