Abstract

A thermoplastic polymer composition comprises a thermoplastic polymer and a compatibilizing agent comprising a fulvene moiety or a fulvene-derived moiety. A heterophasic polymer composition comprises a propylene polymer phase, an ethylene polymer phase, and a compatibilizing agent comprising a fulvene moiety or a fulvene-derived moiety.

First claim

What is claimed is:

1 . A thermoplastic polymer composition comprising:
(a) a thermoplastic polymer; and (b) about 50 ppm or more of a compatibilizing agent based on the weight of the thermoplastic polymer and the compatibilizing agent, the compatibilizing agent being selected from the group consisting of compounds comprising a moiety conforming to the structure of Formula (I), compounds comprising a moiety conforming to the structure of Formula (III), and compounds conforming to the structure of Formula (V)

wherein R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of hydrogen, halogens, hydrocarbyl groups, and substituted hydrocarbyl groups, provided adjacent hydrocarbyl groups or substituted hydrocarbyl groups can be combined to form a secondary ring fused to the ring of the moiety; provided at least one of R 1 , R 2 , R 3 , and R 4 is a hydrogen; and R 5 , R 6 , R 7 , and R 8 are independently selected from the group consisting of halogens.

2 . The thermoplastic polymer composition of claim 1 , wherein R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of hydrogen, halogens, alkyl groups, substituted alkyl groups, aromatic groups, substituted aromatic groups, heteroaromatic groups, and substituted heteroaromatic groups.

3 . The thermoplastic polymer composition of claim 1 , wherein at least two of R 1 , R 2 , R 3 , and R 4 are hydrogens.

4 . The thermoplastic polymer composition of claim 1 , wherein the thermoplastic polymer is a polyolefin polymer.

5 . The thermoplastic polymer composition of claim 4 , wherein the thermoplastic polymer is selected from the group consisting of polypropylenes, polyethylenes, and mixtures thereof.

6 . The thermoplastic polymer composition of claim 1 , wherein the compatibilizing agent is present in the composition in an amount of about 100 ppm or more based on the weight of the thermoplastic polymer and the compatibilizing agent.

7 . The thermoplastic polymer composition of claim 1 , wherein the compatibilizing agent is a compound conforming to the structure of Formula (X) below

wherein R 11 and R 12 are individual substituents independently selected from the group consisting of hydrogen, alkyl groups, substituted alkyl groups, alkenyl groups, substituted alkenyl groups, amine groups, substituted amine groups, aromatic groups, substituted aromatic groups, heteroaromatic groups, and substituted heteroaromatic groups or R 11 and R 12 together form a single substituent selected from the group consisting of aromatic groups, substituted aromatic groups, heteroaromatic groups, and substituted heteroaromatic groups.

8 . The thermoplastic polymer composition of claim 7 , wherein R 1 , R 2 , R 3 , and R 4 are independently selected from the group consisting of hydrogen, halogens, alkyl groups, substituted alkyl groups, aromatic groups, substituted aromatic groups, heteroaromatic groups, and substituted heteroaromatic groups.
