Synthesis Process

The preparation of rubber-modified organosilicon resins typically involves multiple chemical reactions. First, prepolymers are formed by reacting siloxanes with unsaturated monomers containing double bonds (e.g., acrylates). Then, cross-linking agents (such as peroxides) are added to initiate the polymerization of the prepolymers, forming a three-dimensional network structure. During this process, rubber molecules are grafted or covalently bonded to the organosilicon chains, imparting the resin with the elasticity of rubber and the high-temperature resistance and chemical durability of organosilicon.
