Abstract

A composition and method for increasing the hydrolytic stability of a stabilizer composition comprising a first phosphite, a second phosphite, an optional phosphonite and an acid scavenger.

Claims (15)

1. A thermoplastic resin composition comprising a thermoplastic resin and a phosphite stabilizer composition with enhanced hydrolytic resistance, said phosphite stabilizer composition comprising:

a first phosphite of the structure

wherein R 1 , R 3 , R 8 , and R 10 are selected from alkyl groups having from 1 to 8 carbon atoms; R 2 , R 4 , R 5 , R 6 , R 7 and R 9 are hydrogen;

an optional first phosphonite of the structure

wherein R 1 , R 3 , R 8 , and R 10 are selected from alkyl groups having from 1 to 8 carbon atoms; R 2 , R 4 , R 5 , R 6 , R 7 and R 9 are hydrogen; n is 2;

a second phosphite of the structure

wherein R 11 , R 13 , R 15 , R 16 and R 17 are selected from alkyl groups having from 1 to 8 carbon atoms, and R 12 and R 15 are hydrogen;

and an acid scavenger,

wherein the first phosphite is present from 82 to 87 weight percent, the second phosphite is present from 6 to 11 weight percent and the acid scavenger is present from about 1 to about 10 weight percent, each based on the total weight of first phosphite, second phosphite, acid scavenger and optional first phosphonite.

2. The thermoplastic resin composition according to claim 1 wherein the acid scavenger is selected from the group consisting of calcium stearate, zinc stearate, calcium lactate, calcium stearoyl iactylate, zinc oxide, and natural and synthetic hydrotalcites.

3. The thermoplastic resin composition according to claim 2 wherein the acid scavenger is selected from the group consisting of natural and synthetic hydrotalcites.

4. The thermoplastic resin composition according to claim 1 wherein the phosphite stabilizer composition is prepared by cold extrusion or hot extrusion of a mixture of the first phosphite, second phosphite, acid scavenger and optional first phosphonite.

5. The thermoplastic resin composition according to claim 4 wherein the phosphite stabilizer composition is prepared by cold extrusion of a homogenized mixture of the first phosphite, second phosphite, acid scavenger and optional first phosphonite.

6. The thermoplastic resin composition according to claim 5 wherein the phosphite stabilizer composition is in the form of pellets prepared by feeding the homogenized mixture of the first phosphite, second phosphite, acid scavenger and optional first phosphonite into a pellet mill to form pellets.

7. The thermoplastic resin composition according to claim 3 wherein the acid scavenger is magnesium aluminum hydrotalcite.
