Poly(methyl methacrylate) composition |
摘要 |
An impact resistant poly(methyl methacrylate) composition which comprises a solid external phase and a discrete microdispersed solid internal phase with refractive indices in the range of about 1.45 to about 1.55. Said composition is prepared by polymerizing methyl methacrylate monomer, co-monomer mixture or sirup thereof in the presence of a microdispersion therein of a cross-linked graft polymer prepared by copolymerizing a mixture of acrylic or methacrylic ester, selected vinyl substituted monomer and a selected polyfunctional monomer. The composition of this invention can be particularly suitable for use where clear sheet glass is used and where a clear plastic material is desired having good impact strength and optical properties.
