DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) A no. of carboxypropyl-terminated poly(siloxane)s were prepd. 158465-59-9 and 25037-57-4 are cas registry numbers of chemicals which are used as reagents here. using equilibration polymn. reactions. Dimethyldichlorosilane hydrolyzate, DDSH, was applied as a substitute for the otherwise used cyclic siloxane monomers. As DDSH contains YSi-OH end-groups, it was of interest to analyze the obtained linear polymers with regard to the kind and amt. of their terminating units. In order to clarify this question, the IR and 1H NMR spectroscopy, end-group anal., vapor pressure osmometry and GPC detection methods were used. All the results showed that the polymers obtained from DDSH were carboxypropyl-terminated. .
