| titleOfInvention | Highly flexible polycarbonate resin |
| abstract | The present invention relates to a high-flow polycarbonate resin, more specifically, a part of the bisphenol A derivative constituting the polymer chain is replaced by an alkylenedicarboxylic acid and p-oxybenzoic acid represented by the following formula (1), By replacing some of the hard bisphenol A derivative components present in the flexible alkylene chains, the low impact strength and melt flow index were improved while maintaining the excellent properties of the polycarbonate resin, making them suitable for injection molding of thin and complex structures. And p-oxybenzoic acid is introduced into the polymer chain, thereby making it difficult to break the polymer chain by the long alkylene chain, thereby inhibiting the intermolecular twist to maximize the processing effect. It is about.n n n [Formula 1]n n n HOOC-A-COOHn n n In Formula 1, A represents an alkyl group having 9 to 20 carbon atoms. |
