| titleOfInvention | Thermal Resistant Copolymer Resin and Method for Preparing the Same |
| abstract | The present invention relates to a method for producing a copolymer resin containing a maleimide monomer by a continuous block or solution polymerization method, 20 to 60 parts by weight of an aromatic vinyl monomer and a small amount of initiator A and unsaturated dicarboxylic acid Mixture B, in which 10 to 30 parts by weight of the anhydride monomer and 20 to 60 parts by weight of ketone solvent are present, is separately added to the first step of performing a copolymerization reaction between the aromatic vinyl monomer and the unsaturated dicarboxylic acid anhydride monomer. In addition, in order to prepare a copolymer resin having an imide-based substituent having a constant composition, a mixture of 10 to 20 parts by weight of a primary amine-based monomer and a small amount of reactive active catalysts is added to a continuous second to cause an imide substitution reaction. The process takes place. The reaction temperature is in the range of 60 to 200 ° C. in the first step and 100 ° C. to 250 ° C. in the second step, and a heat resistant copolymer can be prepared according to the above method.n n n At this time, in order to prevent the generation of the aromatic vinyl homopolymer produced in the second step, a polymerization inhibitor is used to minimize the addition reaction to produce a copolymer resin having excellent heat resistance. |
