ABSTRACT:
Alkoxy silane compounds such as vinyl-triethoxy-silane are more readily grafted to block copolymers in the presence of an amount of zinc oxide between about 0.15% and 1.5% by weight of the block copolymer. The silane modified block copolymer prepared with zinc oxide exhibits greater resistance to gel formation than silane-modified block copolymer prepared without the zinc oxide.
