Claims (4)
- 아크릴산 그라프트 다당류 공중합체의 알카리금속염을 제조함에 있어서, 다당류를 알콜과 함께 가열하여 용해시키고 서서히 냉각시킨다음, 여기에 아크릴산계 단위체 또는 이와 비닐 공단위체의 혼합물과 산화-환원 촉매혼합물을 넣고 그라프트 반응을 시킨후, 상기 알콜을 진공증류 제거하고 알카리수로 중화시키는 것을 특징으로 하는 아크릴산 그라프트 다당류 공중합체의 알카리금속염을 제조하는 방법.
- 제1항에 있어서, 상기 알콜로서는 탄소수 3∼9의 노말알콜 또는 이소알콜을 상기 다당류에 대해 5∼95%농도의 것을 사용하는 것을 특징으로 하는 아크릴산 그라프트 다당류 공중합체의 알카리금속염을 제조하는 방법.
- 제1항에 있어서, 상기 다당류와 알콜의 가열용해는 60∼90℃에서 2∼40시간 시행함을 특징으로 하는 아크릴산 그라프트 다당류 공중합체의 알카리금속염을 제조하는 방법.
- 제1항에 있어서, 상기 그라프트 반응은 질소기류하에서 25∼50℃의 온도를 유지하면서 2∼40시간 반응시키는 것을 특징으로 하는 아크릴산 그라프트 다당류 공중합체의 알카리금속염을 제조하는 방법.
