Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
87 words
An improved liquid stabilizer for vinyl halide resins which comprises 0.5 to 18% by weight of (a) a Group II metal halide; 0.25 to 6% by weight of (b) sufficient water to dissolve said metal halide; and 44.25 to 99.25% by weight of (c) an ethoxylated alkylphenol of the formula ##STR5## wherein R 1 is an alkyl radical containing from 6 to 18 carbon atoms, R 2 is hydrogen or an alkyl radical as defined for R 1 and n is an integer from 1 to 5.
Claim 2
Dependent Claim
87 words
An improved liquid stabilizer for vinyl halide resins which comprises 0.5 to 18% by weight of (a) a Group II metal halide; 0.25 to 6% by weight of (b) sufficient water to dissolve said metal halide; and 44.25 to 99.25% by weight of (c) an ethoxylated alkylphenol of the formula ##STR5## wherein R 1 is an alkyl radical containing from 6 to 18 carbon atoms, R 2 is hydrogen or an alkyl radical as defined for R 1 and n is an integer from 1 to 5.
Claim 3
Dependent Claim
89 words
The liquid stabilizer of claim 1 which additionally contains up to about 55% by weight of a member (d) selected from the group consisting of (1) a liquid fatty acid containing 4 to 18 carbon atoms, (2) a polyglycerol partial ester derived from a polyglycerol containing 2 to 10 condensed glycerol units and having not more than 75% of the available hydroxyl groups esterified with an aromatic or aliphatic monocarboxylic acid containing 6 to 24 carbon atoms and (3) mixtures of said liquid fatty acids and polyglycerol partial esters.
Claim 4
Dependent Claim
60 words
The liquid stabilizer of claim 1 wherein (a) is selected from the group consisting of zinc chloride, magnesium chloride, calcium chloride and barium chloride and in the formula for (c) R 1 is an alkyl radical containing 8 to 12 carbon atoms located in the para position, R 2 is hydrogen and n is an integer from 2 to 4.
Claim 5
Dependent Claim
32 words
The liquid stabilizer of claim 3 wherein (a) is zinc chloride or a mixture of zinc chloride with magnesium chloride, calcium chloride or barium chloride and (c) is ethoxylated octyl- or nonylphenol.
Claim 6
Dependent Claim
60 words
The liquid stabilizer of claim 2 wherein (a) is selected from the group consisting of zinc chloride, magnesium chloride, calcium chloride, and barium chloride and in the formula for (c) R 1 is an alkyl radical containing 8 to 12 carbon atoms located in the para position, R 2 is hydrogen and n is an integer from 2 to 4.
Claim 7
Dependent Claim
59 words
The liquid stabilizer of claim 5 containing 1.5 to 12% (a), 0.5 to 4% (b), 40 to 83% (c) and 15 to 45% (d) wherein the liquid fatty acid contains 9 to 18 carbon atoms and the polyglycerol ester has no more than 50% of the hydroxyl groups esterified with a fatty acid containing 12 to 18 carbon atoms.
Claim 8
Dependent Claim
34 words
The liquid stabilizer of claim 6 wherein (a) is zinc chloride or a mixture thereof with magnesium chloride, calcium chloride or barium chloride, (c) is ethoxylated octyl- or nonylphenol and (d) is oleic acid.
Claim 9
Dependent Claim
49 words
The liquid stabilizer of claim 6 wherein (a) is zinc chloride or a mixture thereof with magnesium chloride, calcium chloride or barium chloride, (c) is ethoxylated octyl- or nonylphenol and (d) is a mixture of oleic acid and a polyglycerol partial ester derived from predominantly C 18 fatty acids.
Claim 10
Dependent Claim
29 words
A vinyl halide polymer resin stabilized with the liquid stabilizer of claim 1 so that about 0.01 to 2% of the Group II metal is present in the resin.
Claim 11
Dependent Claim
17 words
The resin of claim 9 wherein the vinyl halide polymer is a polyvinyl chloride homopolymer or copolymer.
Claim 12
Dependent Claim
88 words
The resin of claim 10 plasticized with epoxidized soybean oil and stabilized with a liquid stabilizer in an amount such that the resin contains about 0.05 to 0.5% of the Group II metal, said liquid stabilizer containing about 1.5 to 12% zinc chloride or mixture thereof with magnesium chloride, calcium chloride or barium chloride, 0.5 to 4% water, 40 to 83% ethoxylated octyl- or nonylphenol and 15 to 45% oleic acid or mixture of oleic acid with a polyglycerol partial ester derived from predominantly C 18 fatty acids.
