| description | Disclosed are: a crystallizing method of a high heat-resistant polycarbonate copolymer using a nucleating agent, which effectively crystallizes a polycarbonate by using a nucleating agent to have small loss of reactants, and can manufacture the polycarbonate having excellent physical properties as having a high glass transition temperature; and a method for manufacturing a high molecular weight copolymer using the method. Provided is the crystallizing method of the high heat-resistant polycarbonate copolymer using the nucleating agent, which comprises the following steps: (A) melt polycondensing an amorphous high heat-resistant polycarbonate prepolymer by a non-phosgene method using a first aromatic hydroxy compound, a second aromatic hydroxy compound and an aryl carbonate; (B) surface-crystallizing the polycarbonate prepolymer using the nucleating agent; and (C) solid-phase-polymerizing dried crystalline polycarbonate prepolymer.
결정핵제를 이용하여 폴리카보네이트를 효과적으로 결정화하므로, 반응물 손실이 적으며, 높은 유리전이온도를 가짐에 따라 물성이 우수한 폴리카보네이트를 제조할 수 있는 결정핵제를 이용한 고내열 폴리카보네이트 공중합물의 결정화 방법 및 이 방법을 이용한 고분자량의 공중합물 제조방법이 개시된다. (A) 제1방향족 히드록시 화합물, 제2방향족 히드록시 화합물 및 아릴 카보네이트를 이용하여 비결정성 고내열 폴리카보네이트 프리폴리머를 비포스겐법에 의해 용융 중합하는 단계; (B)상기 폴리카보네이트 프리폴리머를 결정핵제를 사용하여 표면 결정화하는 단계; (C)상기 건조된 결정성 폴리카보네이트 프리폴리머를 고상중합하는 단계를 포함하는 결정핵제를 이용한 고내열 폴리카보네이트 공중합물의 결정화 방법을 제공한다. |
