Abstract
Using the hydrosilylation reaction between 1,4-bis(dimethylsilyl)dihydronap hthalene and alpha,omega -divinyl-divinyl-dimethylsiloxanes with hexachloro platinic acid as catalyst, new and important segmented prepolymers with rea ctive end groups were obtained. Ethylene bridges between hard naphthalene a nd soft siloxane segments were formed. The reaction was monitored by IR spe ctrometry These compounds were characterized by H-1-NMR, C-13-NMR and GPC a nalyses.
