Method of plasma initiated polymerization |
摘要 |
An ionized gas plasma is established in an electrical field in contact with a non-vapor volume of monomer (liquid and/or solid). The plasma creates active polymerization sites in the monomer volume to initiate propagation of polymerization therein. After initiation, the partially-polymerized monomer volume is postpolymerized in the absence of the ionized gas plasma to yield a very high molecular weight polymer which may be essentially free of cross-linking in desirable forms including commercial quantities of bulk self-supporting polymer or a coating. Suitable monomers include liquid vinyl monomers (e.g., methyl, methacrylate) and solid crystalline monomers (e.g., 1,3,5-trioxane).
