Monofunctional monomer having cage oligosiloxane structure and method of making

摘要

A novel monofunctional monomer having a cage oligosiloxane structure is represented by formula (1) wherein X is a polymerizable oxygen-containing C₁-C₄₀ group, R¹ is a C₁-C₂₀ saturated hydrocarbon group, C₆-C₂₀ aromatic hydrocarbon group, C₁-C₂₀ organoxy group or halogen atom, and R is a non-polymerizable monovalent C₁-C₄₀ hydrocarbon group which is optionally halogenated. The monomer has improved compatibility with various solvents and polymerizable monomers. A method for preparing the same is also provided.;
