小青蛙呱呱呱关于牵牛花的作文摘要：PURPOSE:A clear plastic that obtained by adding a specific amount of an acid anhydride to a monomer mix of a monomer forming a straight-chain macromolecule and a crosslinking polyfunctional
monomer, further a monomer bearing epoxy groups and polymerizing them, thus showing high clearity and chemical resistance. CONSTITUTION:At least one of monomers who homopolymer has a straight chain structure such as methyl methacrylate is combined with up to veral % of a crosslinking polyfunctional monomer such as diallyl phthalate, further along with a monomer for improving refractive index such as styrene. The resultant multicomponent monomer mix is further combined with a monomer with 2 or more functional groups at least one of which is epoxy such as allyl glycidyl ether, additionally with an acid anhydride such as maleic anhydride in an amount of 20wt% bad on the equivalent amount of the epoxy groups. Then, a polymerization initiator is added to the mixture to effect polymerization, thus producing the objective clear plastic with higher than 70% transmittance in the visible region.思想品德自我评价
