Polyolefins, polyolefin blends and elastomer-modified polyolefins with increased surface polarity
First Claim
Patent Images
1. Polyolefins, polyolefin blends and elastomer-modified polyolefins, having a polar surface, wherein the surface polarity is imparted by an AB block copolymer of a formula ##STR9## wherein R1 groups are same or different and represent alkyl groups with 1 to 8 carbon atoms, with the exception of the t-butyl group;
- R2 groups are --(CH2)p groups, in which p is a number from 2 to 6;
R3 group is a chain regulator, and is free of active hydrogen atoms; and
n and m are same or different and in each case have an average numerical value of not less than 3.
