SILANE COPOLYMER

Polygermanes and germane-silane polymers were prepared similarly. Polygermanes from the electroreduction of dichlorophenylbutylgermane showed typically a molecular weight of Mn = 19900 (10% yield). Germane-silane copolymers showed similar M values. The Ge/Si ratio in mixed polymers was roughly proportional to the ratio of monomers... [Pg.714]

A magnesium sacrificial anode is also effective for the synthesis of Si-Ge and Ge-Ge bonds. This method is quite successful for the preparation of polygermanes and germane-silane copolymers [Eq. (49)] [183]. Polygermanes were also prepared by conventional electrochemical reduction of dihalogermanes using a Pt cathode and an Ag anode [184]. [Pg.787]

Silane copolymers which contain dimethysilane units (4.96) are rapidly photodegraded under UV irradiation [173,2330], When the copolymers were irradiated in an argon atmosphere some crosslinking took place with simultaneous chain scission. Copolymers with aryl groups attached to silicon undergo more photocrosslinking in argon than those without aryl substituents ... [Pg.330]

The germane-silane copolymers, 15, are not block copolymers. They were prepared with germanium mole fractions of 0.16 (M = 17,000) and 0.45 (M = 20,600) and exhibited values at 330 nm and 335 nm, respectively. An almost linear correlation exists between and the germanimn mole fraction, when compared to polygermane (X ax = 355 nm) 26,27.57 polysilane (X ax = 325 nm). ... [Pg.231]
