CR 39 化学特性,用途語,生産方法
使用
The homopolymer (CR 39 polymer) is suitable for the production of cast sheets, lenses, and other articles that have excellent resistance to scratching, impact, and heat as well as outstanding optical properties. This polymer is resistant to common solvents with the exception of oxidizing acids. It is produced in the United States by PPG Ind. Even better qualities can be obtained by reacting CR 39 monomer with other monomers, such as methyl methacrylate [80-62-6] or triallyl isocyanurate [1025-15-6]. These copolymers are used for the production of light-weight lenses with very hard surfaces and high refractive indices.
