PURPOSE:To obtain the subject material having transparency, no strain, toughness and excellent mechanical strength and hardness by forming crosslinked network structure with specific crosslinking agent. CONSTITUTION:The aimed material is composed of a copolymer of crosslinking agent (e.g. 4-vinylbenzyl methacrylate) expressed by the formula (R<1> is H or methyl), preferably styrene-based monomer and acrylic monomer and/or methacrylic monomer [e.g., methyl (meth)acrylate]. |
