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