Claims (7)
- 리그닌을 인산 완충 용액에 부유시키고, 여기에 리그닌 분해효소를 첨가하여, 리그닌을 탈메칠화한 뒤, 탈메칠화된 리그닌에 과산화수소를 서서히 적하 첨가하여 중합시키는 것을 특징으로 하는 리그닌 중합체의 제조방법.
- 제1항에 있어서, 상기한 리그닌은, 펄핑의 폐액, 목재 당화의 부산물로 부터 얻어지는 것임을 특징으로 하는 리그닌 중합체의 제조방법.
- 제2항에 있어서, 상기한 리그닌인 자작나무의 크라프트 펄핑의 부산물로 얻어진 크라프트 리그닌인 것을 특징으로 하는 리그닌 중합체의 제조방법.
- 제1항에 있어서, 상기한 리그닌 분해효소는 박테리아, 식물, 곰팡이 등에서 얻어지는 효소임을 특징으로 하는 리그닌 중합체의 제조방법.
- 제4항에 있어서, 상기한 효소가 코리오러스 버시콜라(Coriolus versicolor)의 연부후균으로 생산된 효소임을 특징으로 하는 리그닌 중합체의 제조방법.
- 리그닌을 인산완충 용액을 부유시키고 여기에 리그닌 분해효소를 첨가하여, 리그닌을 탈메칠화한 뒤, 탈메칠화된 리그닌에 과산화수소를 서서히 적하 첨가하여 중합체로 된 접착제.
- 제6항에 있어서, 상기 접착제가 목재 접합용 접착제인 것을 특징으로 하는 리그닌 중합체로 된 접착제.
