Unsaturated polyester-based bulk molding compounds with the addition of new sunscreens in polymer form are disclosed. The sunscreen used in the present invention is 2-hydroxy-4-acryloyloxybenzophenone, 2- [3- (2H-benzotriazol-2-yl) -4-hydroxyphenyl] ethyl methacrylate, 4-acryloyl-1,2,2,6, As 6-pentamethyl-piperidinyl, these three monomers are used in copolymerization with styrene or methyl methacrylate.n n n According to the present invention, the outdoor use of the bulk molding compound can be freely used, and workability and moldability are improved by using polyvinyl alcohol fibers instead of the conventional glass fibers. |
