摘要:
An impact resistant methyl methacrylate resin is obtained by polymerizing 40 to 99 percent by weight of an unsaturated monomer mixture (A) comprising (a) 50 to 100 percent by weight of methyl methacrylate and (b) 50 to 0 percent by weight of at least one unsaturated monomer copolymerizable with methyl methacrylate in the presence of 60 to 1 percent by weight of an ethylene copolymer (B) containing epoxy group.
摘要:
A reinforced polyolefin composition which comprises a polyolefin, glass fibers and an ethylene-unsaturated glycidyl monomer-ethylenically unsaturated monomer terpolymer obtained by polymerizing 35 to 95.9 parts by weight of ethylene with 0.1 to 20 parts by weight of an unsaturated glycidyl monomer and 4 to 45 parts by weight of any other polymerizable ethylenically unsaturated monomer, containing the unsaturated glycidyl monomer unit in an amount of 1 to 45% by weight and the ethylenically unsaturated monomer unit in an amount of 4 to 45% by weight and having an intrinsic viscosity of 0.1 to 4.5 dl/g in tetralin solution at 135*C; the contents of the glass fibers and of the ethylene-unsaturated glycidyl monomer-ethylenically unsaturated monomer terpolymer being respectively 5 to 60% by weight and 0.1 to 25% by weight (based on the total weight of the composition).
摘要:
A cured rubber composition, which is obtained by curing a composition consisting essentially of an amorphous ethylenepropylene rubber and a fluorine-containing ethylene polymer with an organic peroxide as a curing agent. The cured rubber composition is excellent in heat, chemical, oil and solvent resistance, and hence can be used portions where the convertional ethylene-propylene rubber have not been usable.
