Summary
Comb-like polysiloxanes with pendant chains of the type (CH2)3(OCH2 CH2)nOH (n=0, 8 or 15) were synthesized by hydrosilylation of poly(methylsiloxane) with the corresponding monoallyl glycols in which the hydroxyl group was protected with tetrahydropyran. The polymers were characterized by1H and29Si NMR, and by GPC and DSC. A considerable fraction of small cycles is formed for the n=o compound during the deprotection reaction. Side chain crystallization occurs but is slower than for polymers containing side chains with terminal methoxy groups.
