Abstract
본 발명은 하기 일반식(Ⅰ) 및 (Ⅱ)의 단위체로 구성된 폴리에테르에스테르 탄성중합체를 제조함에 있어서, 에스테르 교환반응 단계에서 하기 일반식(Ⅳ)로 표현되는 디카르복실산 금속염을 탄성체 기준으로 0.1∼15중량% 투입하여 중합체를 제조한 다음, 하기 일반식(Ⅲ)으로 표현되는 유기 포스파이트계 화합물을 탄성체 기준으로 0.05∼10중량% 혼합하여 용융훈련하고 토출함을 특징으로 하는 열안정성 및 가수분해 안정성을 향상시킨 폴리에스테르에스테르 탄성중합체의 제조방법에 대한 것이다.In the present invention, in preparing a polyether ester elastomer composed of units of the following general formulas (I) and (II), the dicarboxylic acid metal salt represented by the following general formula (IV) in the transesterification step is used as an elastomer basis. 0.1 to 15% by weight of the polymer prepared to prepare a thermal stability, characterized in that the organic phosphite-based compound represented by the following general formula (III) is melt-trained and discharged by mixing 0.05 to 10% by weight based on the elastomer The present invention relates to a method for producing a polyester elastomer having improved hydrolytic stability.
여기에서, R1, R2는 분자량 400이하인 디카르복실산으로부터 카르복실기가 제거된 2가 라디칼이며, D는 분자량 250이하인 짧은 고리 디올로부터 수산기가 제거된 2가 라디칼이고, G는 분자량 400∼4,000인 긴고리 에테르글리콜로부터 수산기가 제거된 2가 라디칼이다.Here, R 1 and R 2 are divalent radicals having a carboxyl group removed from a dicarboxylic acid having a molecular weight of 400 or less, D is a divalent radical having a hydroxyl group removed from a short ring diol having a molecular weight of 250 or less, and G is a molecular weight of 400 to 4,000. It is a divalent radical from which hydroxyl group was removed from phosphorus long ring ether glycol.
여기에서, R3및 R4는 치환되거나 또는 치환되지 않은 알킬, 아릴 또는 시이클로알킬, 라디칼이다.Wherein R 3 and R 4 are substituted or unsubstituted alkyl, aryl or cycloalkyl, a radical.
〔(-O3S)xR5(CO2-)2〕M (Ⅳ)((-O 3 S) xR 5 (CO 2- ) 2 ) M (IV)
이때, M은 알칼리 금속 또는 알칼리 토금속 양이온 이고, R5은 탄소수가 2∼30개인 방향족, 지방족 또는 지방족환고리 화합물이며, x는 0 또는 1이다.In this case, M is an alkali metal or alkaline earth metal cation, R 5 is an aromatic, aliphatic or aliphatic ring compound having 2 to 30 carbon atoms, and x is 0 or 1.
