Abstract
탈단백화 턴연 고무의 탈중합화에 의해 수득되는, 수 평균 분자량이 2,000내지 50,000인 액체 고무인 탈증합화 천연 고무가 기술되어 있다. 탈중합화 천연 고무의 테조 방법 또한 기술되어 있는데, 이는 탈단백화 천연 고무를 유기 용매중에, 수득되는 용액의 중량을 기준으로 하여 1내지 30중량% 농도가 되도록 용해시키고, 수득된 용액을 금속 촉매는 존재하에 공기 산화시킴으로써 수행된다. 탈중합화 천연 고무는 통상의 가황 고무에서와 동일한 물리적 특성을 제공할수 있다. 천연 고무의특징적인 냄새 또는 색상을 나타내지 않으며, 단백질에 의해 야기되는 즉각적인 앨러지를 유발시키지 않는다.
