흡수성 수지의 제조 방법

통액성 향상제를 실질적으로 첨가하지 않아도, 초기의 가압 하 흡수 속도가 우수한 흡수성 수지의 제조 방법으로서, 특정한 폴리알킬렌글리콜을 첨가하면서, 단량체를 중합하여, 중합 중 또는 중합 후에, 당해 특정 분자량의 폴리알킬렌글리콜이 내재하는 함수 겔상 가교 중합체를 생성하는 공정을 포함하고, 당해 함수 겔상 가교 중합체의 무가압 하 흡수 배율을 소정의 범위에 들어가도록 하고, 최종적으로 얻어지는 흡수성 수지에 대하여 해당 수지의 각종 물성(CRC, AAP, SFC, FSR)을 규정의 범위로 하는 방법을 제공한다.

description 통액성 향상제를 실질적으로 첨가하지 않아도, 초기의 가압 하 흡수 속도가 우수한 흡수성 수지의 제조 방법으로서, 특정한 폴리알킬렌글리콜을 첨가하면서, 단량체를 중합하여, 중합 중 또는 중합 후에, 당해 특정 분자량의 폴리알킬렌글리콜이 내재하는 함수 겔상 가교 중합체를 생성하는 공정을 포함하고, 당해 함수 겔상 가교 중합체의 무가압 하 흡수 배율을 소정의 범위에 들어가도록 하고, 최종적으로 얻어지는 흡수성 수지에 대하여 해당 수지의 각종 물성(CRC, AAP, SFC, FSR)을 규정의 범위로 하는 방법을 제공한다. Provided as a method for producing a water-absorbing resin having an excellent initial water absorption speed under load even substantially without adding a liquid permeability enhancer is a method for producing the water-absorbing resin includes the step of polymerizing a monomer while adding certain polyalkylene glycol thereto so as to generate, during or after the polymerization, a crosslinked hydrogel polymer containing the polyalkylene glycol of a specific molecular weight, in which the crosslinked hydrogel polymer has a centrifuge retention capacity within a given range and a final water-absorbing resin to be obtained has various physical properties (CRC, AAP, SFC, FSR) being within given ranges.
