【Abstract】 Polysiloxanes usually have low surface tension, low glass transition temperature, high hydrophilicity and good heat resistance. In contrast, polyacrylates have poor water repellency owing to their hydrophilicity, and their mechanical properties are often temperature dependent. Interest has been increased in the combination of polyacrylates with polysiloxans during the past decades in order to prepare polymer materials with improved rformance, and these materials have been widely used in many industrial fields such as rubber, plastic, coating, adhesive etc. In this paper, preparation methods of these composite polymers such as blending method, mass polymerization, solusion polymerization and emulsion polymerization were presented, and seeded emulsion polymerization method was emphasized. Main applications of these composite materials with various components or structures were also given. The advanced developments of these materials were reviewed.更多还原
