Notes:
A one-stage method of preparing code-shell particles was developed for the system containing silicone oils and glycidle methacrylate (GMA). Although the formation of core-shell particles for the systems containing silicone oils and methyl methacrylate (MMA) or styrene (ST) is possible in view of thermodynamics, the core-shell particles were not obtained. Factors such as better compatibility of silicone oils with vinyl monomers, higher swelling degree of silicone rubber in the vinyl monomers, and larger addition rate of thevinyl monomers with Si - H during the crosslinking of silicone oil containing vinyl group and Si - H (SVB and SHB) do not favor the formation of core-shell particles. X-ray photoelectron spectrometer (ESCA) was used in determining the formation of core-shell particles. The mechanism of the formation of core-shell particles is discussed. © 1995 John Wiley & Sons, Inc.
