Abstract

Terminally functionalized polymers that are living or pseudo-living polymers reacted with certain allyl glycidyl ethers, or certain allylhalosilanes or combinations thereof, and a process for preparing the terminally functionalized polymers. Rubber-modified polymeric compositions comprising the terminally functionalized polymers.

First claim

What is claimed is:

1. A terminally functionalized polymer comprising the reaction product of a living polymer and at least one component selected from the group consisting of:
(a) an allyl glycidyl ether having the formula (I)
CH 2 ═CHCH 2 OCH 2 —X

wherein X is an epoxy group as follows:

wherein R 1 , R 2 , and R 3 are the same or different, and are selected from hydrogen, alkyl groups having from 1 to 30 carbon atoms or aryl groups having from 1 to 30 carbon atoms;
(b) an allylhalosilane having the formula (II)
CH 2 ═CHCH 2 Si(R 1 R 2 )—X

wherein R 1 and R 2 are the same or different, and are selected from alkyl groups having from 1 to 30 carbon atoms or aryl groups having from 1 to 30 carbon atoms, and X is a halide selected from a chloride, a bromide, and an iodide, and
(c) a combination of (a) and (b);
wherein the living polymer is a homopolymer of a diene monomer.

2. The terminally functionalized polymer of claim 1 wherein the component is allyl glycidyl ether.

3. The terminally functionalized polymer of claim 1 wherein the component is allylchlorodimethylsilane.

4. The terminally functionalized polymer of claim 1 wherein the component is a combination of allyl glycidyl ether and allylchlorodimethylsilane.

5. The terminally functionalized living polymer of claim 1 , wherein the diene monomer is selected from the group consisting of: 1,3-butadiene, isoprene, 2,3-dimethyl-1,3-butadiene, 1,3-pentadiene, or 1,3-hexadiene.

6. A rubber-modified high-impact polymeric composition comprising a polymer comprised of a vinyl aromatic monomer and a rubber dispersed within the vinyl aromatic polymer wherein the rubber is a terminally functionalized polymer comprising the reaction product of a living polymer and at least one component selected from the group consisting of:
(a) an allyl glycidyl ether having the formula (I)
CH 2 ═CHCH 2 OCH 2 —X

wherein X is an epoxy group as follows:

wherein R 1 , R 2 , and R 3 are the same or different, and are selected from hydrogen, alkyl groups having from 1 to 30 carbon atoms, or aryl groups having from 1 to 30 carbon atoms;
(b) an allylhalosilane having the formula (II)
CH 2 ═CHCH 2 Si(R 1 R 2 )—X

wherein R 1 and R 2 are the same or different, and are selected from alkyl groups having from 1 to 30 carbon atoms, or aryl groups having from 1 to 30 carbon atoms, and X is a halide selected from a chloride, a bromide, and an iodide, and
(c) a combination of (a) and (b);
wherein the living polymer is a homopolymer of a diene monomer.

7. The rubber-modified high-impact polymeric composition of claim 6 wherein the component is selected from the group consisting of allyl glycidyl ether, allylchlorodimethylsilane and combinations of the same.

8. The rubber-modified high-impact polymeric composition of claim 6 wherein the rubber is present in an amount of about 3 to about 40 weight % based on total weight of the composition.

9. The rubber-modified high-impact polymeric composition of claim 6 wherein the polymer comprised of the vinyl aromatic monomer is an interpolymer of styrene and acrylonitrile.

10. The rubber-modified high-impact polymeric composition of claim 6 wherein the polymer comprised of the vinyl aromatic monomer is a homopolymer of styrene.

11. The rubber-modified high-impact polymeric composition of claim 6 , wherein the diene monomer is selected from the group consisting of: 1,3-butadiene, isoprene, 2,3-dimethyl-1,3-butadiene, 1,3-pentadiene, or 1,3-hexadiene.
