摘要
标题共聚物的耐冲击性与丙烯酸酯均聚物相比有明显改善,但随着双烯单体含量的降低,共聚物的耐热性和表面硬度有所下降。丙烯酸酯含量为70%的共聚物的吸收紫外光能力最强(<370nm全吸收),含量为5%～10%的共聚物耐吸水性、耐酸耐碱性及耐冲击性最好。
Transparent resins were synthesized from title methacryloyloxyphenyl propane (abbr. bisvinyl-A) homopolymer and its copolymer with styrene. The homopolymer of bisvinyl-A is light(d_4~20 1.19) ,has high surface hardness (pencil hardness 6H),heat resistance (T_8 155℃) and superior optical properties (n_D^20 1. 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).
