摘要： The present invention relates to a process for the production of a polymer comprising the steps of: a) polymerisation of an emulsion comprising a reaction mixture to obtain a polymeric latex; and b) coagulating the polymeric latex by exposing the polymeric latex to one or more coagulant, and isolating the coagulated product to obtain a polymer; wherein the polymeric latex obtained under a) is stored prior to coagulation step b) for at most such a time that the polymeric latex contains ≤500 CFU/ml of pigment-producing organisms as determined in accordance with ASTM D 5465-93 (2012) when subjecting the polymeric latex to coagulation step b). Such process allows for the production of a polymer having a reduced discoloration. The polymers may have a desirable appearance such as an opaque, white appearance.

摘要： The present invention relates to a method of preparing an ASA graft copolymer, a method of preparing a thermoplastic ASA resin composition including the same, and a method of preparing an ASA molded part, and more particularly, to a method of preparing a multilayered ASA graft copolymer including a step of preparing seeds, cores, and shells. According to the method, since a multifunctional carboxylic acid having 20 or more carbon atoms or a salt thereof is introduced as an emulsifier, the content of the emulsifier remaining in a resin may be reduced, thereby providing an ASA resin having excellent thermal stability and appearance characteristics while the inherent physical properties thereof, such as impact resistance and weather resistance, are maintained.
