Abstract:
A composition of matter comprising a polymer having a branch-upon-branch structure and optionally a polymerizable olefinic end group, having the structure: where B=wherein:Bâ€²=Y,B; m=1 to 100, n=0 to 100, p=0 to 100, n+m+p>2; and if m >1, then the m insertions are consecutive or not consecutive; A=anionic initiator moiety R; Q is selected from the group consisting of a covalent bond, R, C(O), and RC(O); Y is selected from the group consisting of R, CO2R, CN, and NR2; W is CZ&boxH;CH2 or a non-polymerizable moiety; Z is CN; and R is selected from the group consisting of unsubstituted and substituted alkyl, vinyl, aryl, aralkyl, alkaryl and organosilanyl groups, the substituents being the same or different and selected from the group consisting of carboxylic acids, carboxylic ester, hydroxyl, alkoxy, primary amino and secondary amino.
