ORGANOMINERAL POLYMERIC MATERIAL

摘要

The material comprises a siliceous mineral framework constituted by the two-dimensional framework of a phyllosilicate and organic radicals having a reactable group which is capable of polymerization, the radicals being linked by Si-O-Si siloxane bonds to the tetrahedral layer of the phyllosilicate from which a fraction of the octahedral layer has been removed. The method of preparation of the material comprises acid hydrolysis of a phyllosilicate for the partial removal of the octahedral layer followed by reaction of the phyllosilicate with an organosilane having at least one reactable organic group which is capable of subsequent polymerization.
