摘要：

Photoaddition of 1,8-dimercaptooctane with 1,1,3,3-tetramethyl-1,3-divinylsiloxane leads to SH or vinyl terminated prepolymers. DC and HPLC investigations showed that the prepolymers are a mixture of oligomers with increasing chain length. The distribution depends on the molar ratio r of the monomers. Their structures are confirmed by NMR spectroscopy and elemental analysis.
