摘要： A two stage emulsion polymerization process for preparing resins having both weather resistance and impact resistance. In the first step, there are copolymerized 100 to 80% by weight of an alkyl acrylate having alkyl containing 2 to 8 carbon atoms; 0 to 20% by weight of a monomer containing a vinylidene group copolymerizable therewith and cross-linking monomer to produce an aqueous dispersion of cross-linked copolymer having degree of swelling above 10, gel content above 80% and average particle size of 0.15 to 0.5 microns. Emulsifier in an amount of 0.05 to 1 % by weight is used. In the second step, 5 to 50 parts by weight of the solid copolymer of the cross-linked polymer of step 1 is polymerized in the presence of 50 to 95 parts by weight of a monomer mixture of at least 50% by weight of aromatic vinyl monomer and less than 50% by weight of vinyl monomer copolymerizable therewith.
