Polyethyleneglycol-bridged polysiloxane gels: Reactivity and structural effects of glycol chain length
Written by sctunisie no commentsPolyethylene glycol-bridged polysiloxane-derived gels were synthesized by hydrosilylation reaction between polymethylhydrosiloxane and polyethylene glycols of different chain lengths. The obtained polymers have been characterized by elemental analysis, by FTIR, 29Si CP-MAS NMR and 13C CP-MAS NMR. 29Si and 13C solid-state analysis allowed to show the presence of unreacted hydroxyl ether groups, the occurrence of side reactions and to calculate the degree of cross-linking in the polymers.
