Methacrylic resin composition. |
摘要 |
<p>Methacrylic resin compositions comprising 1 to 80% by weight of two-layer methacrylic polymer particles dispersed in 20 to 99% by weight of a methacrylic resin, the methacrylic polymer particles having an average particle size of from 20 to 500nm and a glass transition temperature of from 50 to 120 DEG C and comprising an inner layer and an outer layer in a weight ratio of from 1:9 to 9:1, the inner layer comprising a copolymer of 90 to 99.9% by weight of a monofunctional monomer mainly composed of methyl methacrylate and 0.1 to 10% by weight of a polyfunctional monomer having at least two carbon-carbon double bonds per molecule, and the outer layer comprising a polymer of a monofunctional monomer mainly composed of methyl methacrylate are easily processed and are useful in forming moulded articles having good heat distortion resistance, mechanical properties and solvent resistance.</p> |
