## Abstract

Modified olefine polymers of 20 to 98 parts by weight of an olefine homopolymer or copolymer and 0.5 to 80 parts by weight of a polymer containing aliphatic polyester blocks, which polymers are chemically linked through 0.5 to 40 parts by weight of a polymer of a monomer containing olefinic double bonds, a method for their manufacture, and their employment as moulding compositions.

## Claims

### Claim 1

A process for the preparation of modified olefine polymers, wherein 20 to 98 parts by weight of an olefine homopolymer or copolymer, 0.5 to 80 parts by weight of a polymer containing saturated aliphatic polyester blocks and 0.5 to 40 parts by weight of a monomer containing olefinic double bonds are polymerized in the presence of a radical initiator at 50.degree. to 250.degree. C. in the absence of a solvent.

### Claim 2

Modified olefine polymers of 20 to 98 parts by weight of an olefine homopolymer or copolymer and 0.5 to 80 parts by weight of a polymer containing saturated aliphatic polyester blocks, which polymers are chemically linked through 0.5 to 40 parts by weight of a polymer of a monomer containing olefinic double bonds.

### Claim 3

Modified olefine polymers corresponding to formula (II): ##STR4## wherein X.sub.1 and X.sub.2 denote, independently of each other, H, C.sub.1 -C.sub.4 -alkyl, halogen, COOH or a derivative thereof, or acyloxy;
R.sub.1 to R.sub.9 denote, independently of each other, H, alkyl, aryl or alkylaryl;
A and B denote, independently of each other, polyester groups; and
D and E denote, independently of each other, the end groups formed from the stereospecific polymerization of .alpha.-olefines.
