Abstract: Transparent resins were synthesized from title methacryloyloxyphenyl propane (abbr. bisvinyl-A) homopolymer and its copolymer with styrene. The homopolymer of bisvinyl-A is light(d₄²⁰1.19),has high surface hardness (pencil hardness 6H),heat resistance (T₈ 155℃) and superior optical properties (n_D²⁰1.578,transparency 90～91%). But it is too fragile. The property of bisvinyl-A and styrene copolyrner was dependent on the content of bisvinyl-A. Copolymer containing 70% bisvinyl-A has the most absorption of UV-light (with complete absorbtion at<370nm). The copolymer with 5%～10% bisvinyl-A shows an excellent water absorbing resistance,acid and alkali resistance,impact resistance and high refractive index (n_D 1.588).
