| titleOfInvention | Production of thermoplastic resin particle |
| abstract | PURPOSE: To produce expandable thermoplastic resin particles having improved heat resistance, by incorporating a specific styrene-maleic anhydride copolymer resin with a specific compound and a vinyl aromatic monomer in a specific proportion, and reacting them in the presence of a polymerization catalyst and a foaming agent. n CONSTITUTION: 20W50pts.wt. styrene-maleic anhydride copolymer resin, containing 20W30wt% maleic anhydride component, and having 10W250 average polymerization degree, 1W18pts.wt. compound of the formula RX (X is a functional group reactive with dicarbonyloxo group; R is an aliphatic residue having one double bond), e.g. glycidyl acrylate, and a polymerization catalyst, e.g. benzoyl peroxide, are dissolved in 79W32pts.wt. vinyl aromatic monomer, e.g. styrene, and the resultant solution is suspended in an aqueous medium and reacted preferably at 80W90°C for 2W12hr. A foaming agent, e.g. propane, is added to the suspension during or after the reaction to produce the aimed thermoplastic resin particles. n COPYRIGHT: (C)1984,JPO&Japio |
