Claims
- 1. A composition consisting essentially of:
- (a) a thermoplastic polymer;
- (b) 1 to 30 parts, per hundred parts of thermoplastic polymer, of a mixture comprising:
- (i) a silicone-containing material having the formula: ##STR4## wherein R is an alkyl group containing from 1 to 12 carbon atoms, R' is a monovalent organic group containing at least one alkylene oxide unit and an alkoxy, hydroxy, epoxy, carboxy or amino group; x has a value of at least 1 to 500, and y has a value of from 2 to 300, and
- (ii) an organo derivative having at least one group having the formula: ##STR5## wherein Z is either an oxygen or sulfur atom, n is 0 or 1, and R" is selected from the group consisting of R"', ZR"', and ZH where R"' is an alkyl, aryl, alkenyl or alkynyl group containing from 1 to 24 carbon atoms; and
- (c) 0 to 30 parts, per hundred parts of thermoplastic polymer, of an antiblocking agent, wherein (i) and (ii) are present in a ratio of from 50:1 to 1:20.
- 2. The composition of claim 1 wherein from 1 to 10 parts, per hundred parts of thermoplastic polymer, of mixture (b) is present.
- 3. The composition of claim 1 wherein from 1 to 10 parts, per hundred parts of thermoplastic polymer, of an antiblocking agent is present.
- 4. The composition of claim 3 wherein the antiblocking agent is a diatomaceous silica.
- 5. The composition of claim 1 wherein the silicone-containing material has a molecular weight ranging from 1,000 to 20,000.

- 8. The composition of claim 1 wherein y has a value of 2 to 20.
- 9. The composition of claim 1 wherein R is methyl, R' is C.sub.3 H.sub.6 (OC.sub.2 H.sub.4).sub.a OH, x is 50 to 100, y is 4 to 6, and a is 5 to 10.
- 10. The composition of claim 1 wherein (ii) is dodecane phosphonic acid.
- 11. The composition of claim 1 wherein (ii) is zinc dithiophosphate.
- 12. The composition of claim 1 wherein (ii) is an acid phytate salt.
- 13. The composition of claim 1 wherein (ii) is phytic acid.
- 14. The composition of claim 1 wherein (i) and (ii) are present in a ratio of 2:1 to 1:2.
- 15. The composition of claim 1 wherein the thermoplastic polymer is a polyolefin.
- 16. The composition of claim 15 wherein the polyolefin is a polyethylene.
