PROCESS FOR PRODUCING A LOW HYGROSCOPIC METHACRYLIC RESIN |
| 摘要 |
A methacrylic resin having reduced water absorption properties, useful in optical instruments and as information recording substrates, is produced by polymerizing a mixture consisting of (A) 50 to 85% by weight of a methyl methacrylate, (B) 15 to 50 by weight of a cyclohexyl methacrylate and (C) 0 to 30% by weight of the other copolymerizable with said monomer (A) and (B), or partially polymerized product thereof. |
