Method for preparing graft copolymer of methylmethacrylate-butadiene-styrene having superior anti-stress whitening properties

   
   

The present invention relates to a method of preparing an impact-reinforcement agent for polyvinylchloride (PVC) resin having superior anti-stress whitening properties, and specifically to a method for preparing a graft copolymer of methyl-methacrylate-butadiene-styrene (MBS) comprising 3 steps of graft-copolymerizing monomers such as alkylmethacrylate, acrylate, and an ethylene-unsaturated aromatic compound to a rubber latex, in sequence.

Присытствыющий вымысел относит к методу подготовлять вещество удар-podkrepleni4 для смолаы polyvinylchloride (pvc) имея главное анти-usilivaet забеливать свойства, и специфически к методу для подготовлять сополимер прививка метилов-меткрилат-бутадиен-stiroplasta (mbs) состоя из 3 шагов мономеров privivka-copolymerizing such as alkylmethacrylate, акрилит, и этилен-ethylene-unsaturated ароматичная смесь к rubber latex, в последовательности.
