Information on the synthesis of the polyetherimide—polysiloxane block copolymers has not been disclosed. Many other synthetic methods for preparing block copolymers have been described (19,20,25) but are currendy not beheved to be commercially important. [Pg.15]

Also of interest is the polysiloxane-polyetherimide copolymer marketed as Ultem Siltem STM1500, which is considered further in Chapter 29. [Pg.526]

Block copolymers containing polysiloxane segments are of great interest as polymeric surfactants and elastomers. Polycondensation and polyaddition reactions of functionally ended prepolymers are usually employed to prepare well-defined block copolymers. The living polystyrene anion reacts with a,co-dichloropoly(dimethyl-siloxane) to form multiblock copolymers398. ... [Pg.35]

Because of the interest in the polyurethane industry with respect to grafting, extensive studies were made on the preparation of polydimethyl sfloxane-polyoxy-alkylene block copolymers by coupling of polyethergtycol and polysiloxanes with functional terminal groups408. ... [Pg.37]
