Title:
POLAR GROUP-CONTAINING CYCLIZED RUBBER AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2004/065427
Kind Code:
A1
Abstract:
A polar group-containing cyclized rubber which greatly improves adhesion between a coating material and a formed body of a nonpolar polymer such as polypropylene or polyethylene is disclosed. A method for producing such a polar group-containing cyclized rubber is also disclosed. The polar group-containing cyclized rubber has a polar group at the end of the polymer chain and a weight-average molecular weight of 1,000-1,000,000. Such a polar group-containing cyclized rubber is obtained by cyclizing a conjugated diene polymer having a polar group at the end of the polymer chain.
