| titleOfInvention | Manufacturing method of thermoplastic resin excellent in whiteness |
| abstract | The present invention is 20 to 50 parts by weight of the styrene monomer, 50 to 30 parts by weight of the acrylonitrile monomer, 30 to 60 parts by weight of polybutadiene latex, 0.2 to 0.6 parts by weight of the oxidation-reduction polymerization initiator in one step graft polymerization, 2 20 to 50 parts by weight of a mixture of an aromatic vinyl monomer and an unsaturated nitrile monomer was added to prepare a two-stage graft polymer, and then 0.01 to 1% by weight of an antioxidant in an emulsion state was added and solidified with a metal salt. After completion, it excludes polymerization additives that can remain in the final product and have a bad effect on color, and it can improve the retention thermal stability at high temperatures. Unlike conventional ABS resins, there is no yellowing phenomenon and natural color whiteness. Improved thermoplastics can be prepared. |
