PROCESS FOR PREPARING POLYMER RESINS OF HIGH IMPACT RESISTANCE

摘要

a process for preparing polymer resins of high impact resistance which comprises coagulating a latex of a rubbery polymer, optionally grafted with at least one ethylenic monomer, in the presence of a suspension stabilizer and a coagulating agent to form a stable aqueous suspension of coagulated particles of the rubbery polymer, adding at least one ethylenic monomer to the aqueous suspension and subjecting the resultant mixture to suspension polymerization. In this manner, the suspension polymerization can be accomplished successfully even when the type and amount of the rubbery polymer are varied within a broad range.
