  • Methacrylate resin with excellent discoloration-resistance and transparency and method for preparing the same
    Patent number: 8133958
    Abstract: One aspect of the invention relates to a methacrylate resin prepared by suspension polymerization using a polyalkylacrylate-acrylic acid as a suspension stabilizer. The suspension stabilizer is used in an amount of about 0.05 to about 0.25 parts by weight per 100 parts by weight of a monomer mixture. Another aspect of the invention relates to a method for preparing a methacrylate resin, which comprises: preparing a mixture by mixing an initiator and a chain-transfer agent with a monomer mixture comprising at least about 50% by weight of alkyl methacrylate; and adding the mixture to an aqueous solution of polyalkylacrylate-acrylic acid to conduct suspension polymerization.
