Abstract
Anionic polyurethane emulsion with pendant -COO- group was synthesized by reacting hexamethylene diisocyanate with polyester prepolymer composed of poly(tetramethylene adipate) glycol and trimellitic anhydride. The effect of ionic group content, 1,4-butanediol content, NCO/OH index on the properties of polyurethane emulsion were evaluated. With increasing ionic group content, the glass transition temperature increased. But the ionic group content had little effect on the melting temperature and total heat of fusion. The crystallinity was found to decrease with the increase in 1,4-butanediol content arid NCO/OH index.

Poly(tetramethylene adipate) glycol과 trimellitic anhydride로 이루어진 폴리에스터 프리폴리머와 hexamethylene diisocyanate를 반응시켜 -COO-기를 가지는 음이온계 폴리우레탄 에멀젼을 합성하였다. 이온기의 함량, 1,4-butanediol함량, NCO/OH index의 변화가 폴리우레탄 에멀젼의 물성에 미치는 영향을 조사하였다. 이온기의 함량이 증가하면 글라스 전이온도는 상승하였으나 융점과 결정융해열에는 거의 영향이 없었다. 한편 결정성은 1,4-butanediol함량과 NCO/OH index가 증가함에 따라 감소하였다.
