Title:
SOL AND GEL COMPRISING ALKOXYSILANES AND POLYROTAXANE
Document Type and Number:
WIPO Patent Application WO/2017/195715
Kind Code:
A1
Abstract:
The invention provides a silica aerogel having desired properties in terms of the heat-insulating property, transparency, and mechanical strength. The invention provides a sol comprising (a) SIR1 n(OR2)4-n (in the formula, R1 and R2 each independently represent a C1-20 linear or branched alkyl group, C3-20 cyclic alkyl group, or optionally substituted phenyl group, n represents an integer of 0-3) and (b) a polyrotaxane obtained by arranging blocking groups so that cyclic molecules are not eliminated at both ends of a pseudopolyrotaxane in which cyclic molecules are included in a manner such that the openings thereof are skewered by linear molecules.
