Abstract

PURPOSE:To obtain the titled polymer, having excellent strength and transparency and suitable as lenses, etc., by subjecting a syrup containing a halogenated aromatic monomer, aromatic monomer containing no halogen, polyfunctional monomer having ethylene glycol chain, etc., and a specific polymer to casting polymerization. CONSTITUTION:The aimed polymer obtained by subjecting a syrup having composition of four components of (A) a radically polymerizable monomer (hereinafter referred to as monomer) having a halogenated aromatic ring in the molecule, (B) a monofunctional monomer having an aromatic ring containing no halogen in the molecule, (C) a polyfunctional monomer having ethylene glycol or propylene glycol chain and (D) a polymer of the components (A) and/or (B) existing within the range of a closed region formed by connecting points (5, 0), (90, 50) and (90, 0) on the X-Y coordinates on the assumption that X% is the ratio of the total number of the component (A) units to the total number of the monomer units and Y% is the ratio of the number of the component (A) units in the component (D) to the total number of the monomer units in the component (D) to casting polymerization.
