发明名称 Telechelic polymers are produced by ozonation degradation of diene polymers
摘要 A low molecular weight, telechelic polymer containing polar internal functionality is produced by (a) treating a copolymer of a polar alpha olefin and a conjugated diene with ozone to degrade the copolymer and form polymer segments which have aldehyde or ketone groups on the chain ends, wherein the copolymer has a random distribution of predominantly 1,4-diene double bonds and the pendant functional groups of the polar alpha olefin are stable to ozone, and (b) further reacting the aldehyde or ketone end groups to provide terminal functionality. The terminal functionality which can be provided includes carboxylic acid groups, primary hydroxyl groups, and amide groups.
