PROCESS FOR PRODUCING A METHACRYLIC RESIN SHAPED ARTICLE HAVING A MAT SURFACE |
| 摘要 |
A novel methacrylic resin shaped article is made of novel compositions comprising (A) 80 to 99.9% by weight of methyl methacrylate polymer or copolymer, which forms continuous phase, and (B) 0.1 to 20% by weight of a polymer obtained from at least one unsaturated monomer of the general formula <IMAGE> wherein R1 is H or methyl group and R2 is a hydrocarbon radical of at least two carbon atoms, a derivative or monomer mixture thereof, the respective refractive indexes (nA) and (nB) of said (A) and (B) polymers satisfying the relation of 0.998</=nB/nA</=1.002. The above shaped article has a latent mat surface, which therefore may be converted to a mat surface merely by means of stretching at a temperature above heat distortion temperature. |
