Preparation and characterization of stable DQ silicone polymer sols
Source abstract
Abstract
Stable DQ silicone polymer sols composed of di (D)- and tetra (Q)-functional alkoxysilanes were prepared by the following methods: (i) co-hydrolysis–condensation between diethoxy(dimethyl)silane (DEDMS) and tetraethoxysilane (TEOS) (DEDMS–TEOS as random copolymer sols), (ii) co-hydrolysis–condensation between poly(dimethylsiloxane) (PDMS) and TEOS (PDMS–TEOS as random block copolymer sol), and (iii) triethoxysilylation of a PDMS-lithium salt (PDMS–TES). The polymer sols were characterized by GPC, NMR, and FT-IR. The differences in properties between the structures were analyzed from their thermal stabilities and by using the swelling test. Thermal stabilities of these polymer sols were increased with the increase in the chain length of the D domain and with decrease in hydrolyzability. The swelling of films via polymer sols was decreased with the increase in the degree of crosslinking in sols.
