Phenyl-modified hybrid prepolymer, phenyl-modified polydimethylsiloxane hybrid pre-polymer and phenyl-modified polydimethylsiloxane hybrid polymer and methods for their production
Phenyl-modified hybrid prepolymer, phenyl-modified polydimethylsiloxane hybrid pre-polymer and phenyl-modified polydimethylsiloxane hybrid polymer and methods for their production
A phenyl-modified polydimethylsiloxane hybrid prepolymer and a phenyl-modified polydimethylsiloxane hybrid polymer, which can control material hardness and surface tackiness in accordance with application and purpose. The phenyl-modified hybrid prepolymer (B) is prepared by subjecting a polydimethylsiloxane having a trialkoxysilyl group at both ends to hydrolysis-condensation reaction with phenyltrialkoxysilane and diphenyldialkoxysilane. The phenyl-modified polydimethylsiloxane-based hybrid prepolymer (C) contains (B), preferably a phenyl-modified hybrid prepolymer prepared by condensation reaction of a polydimethylsiloxane having silanol groups at both terminals with phenyltrialkoxysilane (A) in a solvent. The phenyl-modified polydimethylsiloxane hybrid polymer is obtained by heating and solidifying (C).
