| titleOfInvention | Thermoplastic Resin Compositions With High Gloss And High Impact Resistance And Process For Preparing The Same |
| abstract | The method for producing a thermoplastic resin composition having ultra high gloss and ultra high impact according to the present invention comprises (1) a rubbery solution of a styrene monomer in which a polybutadiene rubber having a viscosity of 20 to 25 cps is dissolved at 25 ° C. in a first reactor; Styrene monomer was added, followed by continuous bulk polymerization by maintaining the average residence time of the raw material solution in the first reactor to be 2-2.5 hours and controlling the polymerization temperature to 125 to 135 ° C; (2) in the second reactor, polydimethylsiloxane is added to the polymer of the first reactor to carry out continuous bulk polymerization so that the solid component is 50 to 80% by weight; And (3) separating the unreacted monomer from the polymer produced in the second reactor to prepare pellets. The ratio of gel component to rubber component in the final resin composition prepared according to the invention ranges from 1.9 to 3.4 and the average rubber particle size ranges from 0.2 to 0.32 μm. In the first reactor, the polybutadiene rubber is dissolved in the solution at a concentration of 7 to 20% by weight, and the rubbery solution of the styrene monomer has a viscosity of 20 to 25 cps at 25 ° C. In addition, the polydimethylsiloxane introduced into the second reactor has a viscosity of 10 to 10,000 cps, and is added at 0.01 to 0.70 wt% based on the reactants of the second reactor. |
