POLYMER COMPOSITIONS, FILM OBTAINED THEREFROM AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A polymer composition for manufacturing a polymethyl methacrylate-based film has a flexibility to be mold to desired shape by sufficient injection or extrusion scratch resistance. CONSTITUTION: A polymer composition for manufacturing a polymethyl methacrylate-based film comprises 80-99.9 parts by weight of a methylmethacrylate monomer, 0.1-20 parts by weight of a silsesquioxane-based polymer with an organic network structure. A manufacturing method of a film comprises a step of adding water and acid into a silane monomer to manufacture the silsesquioxane-based polymer with an organic network structure; a step of adding a methyl methacrylate monomer, polymerization initiator, and releasing agent; and a step of heat-treating the resin.
