Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 53 words
Codispersed particulate lubricant stabilizer compositions for synthetic resins, the particles consisting essentially of the product prepared by blending from about 4 parts to about 1 part polyvalent metal fatty acid soap with from about 1 part to about 4 parts alkylene-bis-(fatty acid amide), and heating until water of reaction is no longer released.
Claim 2
Dependent Claim 53 words
Codispersed particulate lubricant stabilizer compositions for synthetic resins, the particles consisting essentially of the product prepared by blending from about 4 parts to about 1 part polyvalent metal fatty acid soap with from about 1 part to about 4 parts alkylene-bis-(fatty acid amide), and heating until water of reaction is no longer released.
Claim 3
Dependent Claim 38 words
Codispersed particulate lubricant stabilizer compositions according to claim 1 in which the amount of polyvalent metal fatty acid soap is within the range from about 3 parts to about 1 part for each part of alkylene-bis(fatty acid amide).
Claim 4
Dependent Claim 50 words
Codispersed particulate lubricant stabilizer compositions according to claim 1 in which the polyvalent metal fatty acid soap is of a fatty acid having from about ten to about twenty-four carbon atoms, and the polyvalent metal is selected from the group consisting of magnesium, calcium, strontium, barium, zinc, lead and cadmium.
Claim 5
Dependent Claim 73 words
Codispersed particulate lubricant stabilizer compositions according to claim 1 in which the alkylene bis(fatty acid amide) has the formula: ##STR3## wherein: R 1 and R 2 are long chain fatty acid groups having from about nine to about twenty-three carbon atoms; R 3 and R 4 are hydrogen or lower alkyl having from one to about six carbon atoms; and A is an alkylene group having from two to about six carbon atoms.
Claim 6
Dependent Claim 23 words
Codispersed particulate lubricant stabilizer compositions according to claim 4 in which the alkylene bis fatty acid amid is an ethylene bis(fatty acid amide).
Claim 7
Dependent Claim 32 words
Codispersed particulate lubricant stabilizer compositions according to claim 1 in which the polyvalent metal fatty acid soap is a polyvalent metal stearate, and the alkylene bis fatty acid amide is ethylene bis(stearamide).
Claim 8
Dependent Claim 17 words
Codispersed particulate lubricant stabilizer compositions according to claim 1 including codispersed therewith a polyvinyl chloride resin stabilizer.
Claim 9
Dependent Claim 33 words
Codispersed particulate lubricant stabilizer compositions according to claim 7 in which the polyvinyl chloride resin stabilizer is selected from the group consisting of organotin compounds, organic phosphites, phenolic antioxidants, and polyvalent metal phenolates.
Claim 10
Dependent Claim 16 words
Codispersed particulate lubricant stabilizer compositions according to claim 1 including codispersed therewith a hydrocarbon wax lubricant.
Claim 11
Dependent Claim 17 words
Codispersed particulate lubricant stabilizer compositions according to claim 9 in which the hydrocarbon wax is paraffin wax.

Dependent Claim 20 words
Polyvinyl chloride resin compositions comprising a polyvinyl chloride resin and a codispersed particulate lubricant stabilizer composition according to claim 1.
Claim 13
Dependent Claim 19 words
Polyvinyl chloride resin compositions according to claim 11 in which the polyvinyl chloride resin is polyvinyl chloride resin homopolymer.
Claim 14
Dependent Claim 20 words
Polyvinyl chloride resin compositions comprising a polyvinyl chloride resin and a codispersed particulate lubricant stabilizer composition according to claim 7.
Claim 15
Dependent Claim 32 words
Polyvinyl chloride resin compositions according to claim 11 in which the polyvinyl chloride resin stabilizer is selected from the group consisting of organotin compounds, organic phosphites, phenolic antioxidants, and polyvalent metal phenolates.
Claim 16
Dependent Claim 20 words
Polyvinyl chloride resin compositions comprising a polyvinyl chloride resin and a codispersed particulate lubricant stabilizer composition according to claim 9.
Claim 17
Dependent Claim 16 words
Polyvinyl chloride resin compositions according to claim 15 in which the hydrocarbon wax is paraffin wax.
