Block copolymers of polyisobutylene and polydimethylsiloxane |
| abstract |
The present invention is a method for preparing anpolyisobutylene-siloxane block copolymer, said methodncomprising:n (I) lithiatingn (A) a polyisobutylene having one or two terminalnsilanol groups with (B) an organolithium compound; (II) reacting the silanolate-functional polyisobutylenenobtained in step (I) withn (C) a hexaorganocyclotrisiloxane; and (III) capping the siloxanolate-functional block copolymernobtained in step (II) with a compound selected from eithern (D) a silane having at least one hydrolyzablengroup or (E) an acid. |
