Preparation and characterization of "organic-inorganic" hybrides by modification of polymethylhydrosiloxane

Written by sctunisie no comments

Polymethylhydrosiloxane (PMHS) was reacted by modification with 1-hexanol, 1-hexene, 1,6-hexanediol and 1,5-hexadiene. The reaction with the 1-hexanol and 1-hexene was studied in the liquid phase by NMR and infrared. The use of bifunctional reactants such as 1,6-hexanediol and 1,5-hexadiene leads to the formation of polymeric transparent gels that have been characterized by 29Si, 13C MAS-NMR and infrared. The difference of the crosslinking groups for the two systems, Si-O-C versus Si-C bonds, influences the stability of the polymeric materials.
