    • Disclosed is a method for producing a plastic lens having reflow heat resistance at 260° C., which is characterized in that a photosensitive resin composition containing a specific resin and a photopolymerization initiator is molded into a lens shape. The resin is obtained by mining one or more compounds (a) selected from the group consisting of (CH3O)3—Si—(CH2)3—O—CO—C(CH3)═CH2, (CH3O)3—Si—(CH2)3—O—CO—CH═CH2, (CH3O)3—Si—(CH2)x—CH═CH2 (wherein X is 1 or 2), (CH3O)2—Si(CH3)(CH2)3—O—CO—C(CH3)═CH2, (CH3O)2—Si(CH3)(CH2)3—O—CO—CH═CH2 and (CH3O)2—Si(CH3)—(CH2)x—CH═CH2 (wherein X is 1 or 2) with a compound (b) represented by (C6H5)2—Si—(OH)2 such that 50-150 moles of the compounds (a) is mixed per 100 moles of the compound (b), and then polycondensing the mixture at 40-15° C. for 0.1-10 hours in the presence of a catalyst.
    • 公开了一种在260℃下具有回流耐热性的塑料透镜的制造方法,其特征在于,将含有特定树脂和光聚合引发剂的感光性树脂组合物成型为透镜状。 树脂通过采用一种或多种选自(CH 3 O)3 -Si-(CH 2)3 -O-CO-C(CH 3)= CH 2,(CH 3 O)3 -Si((CH 3) (CH 3)3-Si-(CH 2)x -CH 2 CH 2(其中X为1或2),(CH 3 O)2 -Si(CH 3)(CH 2)3 - O-CO-C(CH 3)= CH 2,(CH 3 O)2 -Si(CH 3)(CH 2)3 -O-CO-CH = CH 2和(CH 3 O)2-Si(CH 3) - (CH 2)x-CH = CH2(其中X为1或2)与(C6H5)2-Si-(OH)2表示的化合物(b)的混合,使得每100摩尔化合物(b)混合50-150摩尔的化合物 ),然后在催化剂存在下,将混合物在40-15℃下缩聚0.1-10小时。
