Abstract
Abstract A halogen-containing resin composition comprising a halogen-containing resin having incorporated therein one or more esters derived from one or more fatty acids and one or more polyhydric alcohols containing from 2 to 6 carbon atoms, said fatty acids being expressed by the general formula ##STR1## where at least two of the R 1 , R 2 and R 3 radicals are alkyl radicals and, when two of them are alkyl radicals, the remaining one is hydrogen; and the total number of carbon atoms contained in the R 1 , R 2 and R 3 radicals is in the range of from 18 to 38. The foregoing composition is excellent in lubricity and heat stability, thus causing no occurrence of "plate-out" or "blooming."

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A halogen-containing resin composition comprising a halogen-containing resin having incorporated therein one or more esters which lubricate and heat stablize said resin, said esters being derived from one or more fatty acids and one or more polyhydric alcohols selected from the group consisting of ethylene glycol, propylene glycol, 1,3-butanediol, 1,4-butanediol, glycerol, trimethylolethane, and pentaerythritol, said fatty acids being expressed by the general formula ##STR3## where at least two of the R 1 , R 2 and R 3 radicals are alkyl radicals and, when two of them are alkyl radicals, the remaining one is hydrogen; and the total number of carbon atoms contained in the R 1 , R 2 and R 3 radicals is in the range of from 18 to 38.
Claim 2
Dependent Claim
123 words
A halogen-containing resin composition comprising a halogen-containing resin having incorporated therein one or more esters which lubricate and heat stablize said resin, said esters being derived from one or more fatty acids and one or more polyhydric alcohols selected from the group consisting of ethylene glycol, propylene glycol, 1,3-butanediol, 1,4-butanediol, glycerol, trimethylolethane, and pentaerythritol, said fatty acids being expressed by the general formula ##STR3## where at least two of the R 1 , R 2 and R 3 radicals are alkyl radicals and, when two of them are alkyl radicals, the remaining one is hydrogen; and the total number of carbon atoms contained in the R 1 , R 2 and R 3 radicals is in the range of from 18 to 38.
Claim 3
Dependent Claim
72 words
A composition of claim 1 wherein said halogen-containing resin is a chlorine-containing resin selected from the group consisting of polyvinyl chloride, polyvinylidene chloride, chlorinated polyethylene, chlorinated polypropylene, copolymers of vinyl chloride and vinylidene chloride, copolymers of vinyl chloride and other vinyl monomers, copolymers of vinyliden chloride and other vinyl monomers, copolymers of vinyl chloride, vinylidene chloride and other vinyl monomers, and mixtures of any two or more of the foregoing polymeric materials.
Claim 4
Dependent Claim
31 words
A composition of claim 1 wherein said esters are present in an amount equal to from 0.1 to 3 parts by weight per 100 parts by weight of said halogen-containing resin.
Claim 5
Dependent Claim
12 words
A composition of claim 1 wherein the polyhydric alcohol is ethylene glycol.
Claim 6
Dependent Claim
11 words
A composition of claim 1 wherein said polyhydric alcohol is pentaerythritol.
Claim 7
Dependent Claim
20 words
A composition of claim 1 wherein said fatty acid is a fatty acid having an odd number of carbon atoms.
