Abstract

Copolymers of poly(ethylene-co-acrylic acid) and polydiorganosiloxanes, compositions comprising the same, and articles comprising the copolymers, compositions, or both.

First claim

What is claimed is:

1. A composition comprising:
a) a poly(ethylene-co-acrylic acid) copolymer and
b) 0.1 to 10 wt. % of the functional copolymer of a functional copolymer comprising a poly(ethylene-co-acrylic acid) segment and a covalently bound polydiorganosiloxane segment.

2. The composition of claim 1 comprising 1 to 7 wt. % of the functional copolymer.

3. The composition of claim 1 wherein from 0.001 mol % to 100 mol % of the acrylic acid units in the poly(ethylene-co-acrylic acid) segment are bound to a polydiorganosiloxane segment of the functional copolymer by an ester bond or an amide bond.

4. The composition of claim 1 , wherein from about 0.005 mol % to about 50 mol % of the acrylic acid units in the poly(ethylene-co-acrylic acid) segment are bound to a polydiorganosiloxane segment by an ester or an amide bond.

5. The composition of claim 1 , wherein the functional copolymer is the reaction product of poly(ethylene-co-acrylate) of Formula (I)

and polydiorganosiloxane of Formula (II)

wherein:
each X is independently OH, Cl, Br, R′—NZ or R′—CO, provided at least some occurrences of X are neither R′—NHZ nor R′—CO,
each Y, Y′, and Y″ is independently selected from R, G-OH, G-O(CO)R′, G-NHZ, and G-NZ(CO)R′,
each R is independently alkyl, aryl, or aralkyl,
each G is independently alkylene, arylene, or aralkylene,
each Z is independently hydrogen, alkyl, aryl, or aralkyl,
a and b are both greater than zero and are selected such that 28(a)+72(b) is from about 1,000 to about 100,000, and
p is zero or greater,
q is one or greater, and
p and q are selected such that p+q is from 1 to about 12,000;

and further wherein:
of Y, Y′, and Y″ is G-OH or G-NHZ,
when either Y, Y′, or both Y and Y′ are not R then Y″ is R,
when Y″ is not R then both Y and Y′ are R.

6. The composition of claim 5 , wherein the polydiorganosiloxane has the structure of Formula (III)

7. The composition of claim 5 , wherein the polydiorganosiloxane has structure of Formula (IV)

8. The composition of claim 5 , wherein the polydiorganosiloxane has the structure of

9. The composition of claim 5 , wherein Y″ is R and p is zero.

10. The composition of claim 5 wherein the polydiorganosiloxane has the structure of

11. The composition of claim 10 wherein Y is G-OH or G-NZH and Y′ is R.

12. The composition of claim 10 wherein Y is G-OH or G-O(CO)R′.

13. The composition of claim 10 wherein Y is G-NZH or G-NZ 2 .

14. The composition of claim 5 wherein both Y and Y′ are G-OH.

15. The composition of claim 5 wherein Y is OH and Y′ is OR′.

16. The composition of claim 5 wherein both Y and Y′ are NZH.

17. The composition of claim 5 wherein Y is NZH and Y′ is NZ 2 .

18. The composition of claim 1 further comprising ceramic or transparent microspheres.

19. The composition of claim 1 further comprising a plasticizer in amounts of 0.1 to 4 wt. %.

20. The composition of claim 1 further comprising a wax in amounts of 1 to 5 wt. %.

21. The composition of claim 1 further comprising a dye, pigment of whitening agent.

22. The composition of claim 1 further comprising a C5 hydrocarbon resin in amounts of 5 to 20 wt.
