Abstract

PURPOSE:To make it possible to form a water-resistant material low in hygroscopicity, excellent in dimensional stability and useful as an optical material, by using highly isotactic polymethyl methacrylate or a mixture thereof with highly syndiotactic polymethyl methacrylate. CONSTITUTION:This water-resistant material is formed from highly isotactic polymethyl methacrylate or a mixture thereof with highly syndiotactic polymethyl methacrylate. It is desirable that the former polymethyl methacrylate has an isotacticity >=95%, and the latter one has a syndiotacticity >=80%. The composition of the mixture preferably such that 1-99pts.wt. highly isotactic component is present per 99-1pts.wt. highly syndiotactic component.
