Abstract
Abstract Soaps and ester-soaps of high molecular weight branched- and straight-chain aliphatic monocarboxylic acids obtained from alpha -olefins containing 22 or more carbon atoms are useful lubricants for structural resins. High molecular weight acids useful for the preparation of the soaps and ester-soaps are obtained by the free radical addition of a short chain monocarboxylic acid to C22+ olefin or by ozonization of the C22+ olefin. The products of this invention provide excellent internal-external lubrication for PVC homopolymers and copolymers.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A thermoplastic resin composition comprising polyvinyl chloride homopolymer or copolymer and 0.1 to 5 parts per hundred parts resin of a soap or ester-soap derived from: (a) a mixed, straight-chain aliphatic monocarboxylic acid obtained by the ozonization of a C 22+ α-olefin and containing less than 30% by weight acids having fewer than 21 carbon atoms, less than 20% by weight acids having greater than 35 carbon atoms and 55% by weight or more C 21-35 acids wherein the weight ratio of odd to even carbon content acids in the C 21-35 range is between 1.5:1 and 10:1; (b) a metal compound wherein the metal is selected from the group consisting of alkali metals, alkaline earth metals, amphoteric metals and heavy metals and; (c) an aliphatic hydroxylic compound having 2 to 25 carbon atoms and 1 to 10 primary or secondary hydroxyl groups; said soaps and ester-soaps containing from about 0.1 to 15% by weight of said metal.
Claim 2
Dependent Claim
158 words
A thermoplastic resin composition comprising polyvinyl chloride homopolymer or copolymer and 0.1 to 5 parts per hundred parts resin of a soap or ester-soap derived from: (a) a mixed, straight-chain aliphatic monocarboxylic acid obtained by the ozonization of a C 22+ α-olefin and containing less than 30% by weight acids having fewer than 21 carbon atoms, less than 20% by weight acids having greater than 35 carbon atoms and 55% by weight or more C 21-35 acids wherein the weight ratio of odd to even carbon content acids in the C 21-35 range is between 1.5:1 and 10:1; (b) a metal compound wherein the metal is selected from the group consisting of alkali metals, alkaline earth metals, amphoteric metals and heavy metals and; (c) an aliphatic hydroxylic compound having 2 to 25 carbon atoms and 1 to 10 primary or secondary hydroxyl groups; said soaps and ester-soaps containing from about 0.1 to 15% by weight of said metal.
Claim 3
Dependent Claim
54 words
The thermoplastic resin of claim 1 wherein the mixed, straight-chain aliphatic monocarboxylic acid is obtained by the ozonization of a C 22+ α-olefin wherein at least 90% by weight of the olefins have 22 or more atoms and the metal is selected from the group consisting of lithium, calcium, barium, magnesium, zinc and tin.
Claim 4
Dependent Claim
97 words
The thermoplastic resin composition of claim 2 wherein the mixed, straight-chain aliphatic monocarboxylic acid is obtained by the ozonization of an α-olefin wherein at least 70% by weight of the olefins have 30 or more carbon atoms and the mixed acid product contains less than 20 weight percent acids having fewer than 21 carbon atoms, less than 10 weight percent acids having more than 35 carbon atoms and greater than 70 weight percent C 21-35 acids with the ratio of odd to even carbon content acids in the C 21-35 range being between about 1.75:1 and 4:1.
Claim 5
Dependent Claim
45 words
The thermoplastic resin composition of claim 3 containing about 0.2 to 2.0 phr of the ester-soap wherein the aliphatic hydroxylic compound is selected from the group consisting of ethylene glycol, neopentyl glycol, pentaerythritol, dipentaerythritol, tripentaerythritol, glycerol, diglycerol, triglycerol or tetraglycerol and the metal is calcium.
Claim 6
Dependent Claim
15 words
The thermoplastic resin composition of claim 3 containing about 0.2 to 2.0 phr calcium soap.
Claim 7
Dependent Claim
19 words
