Abstract
Polyurethane elastomers were synthesized from poly(tetramethylene glycol) (PTMG), hexamethylene diisocyanate(HDI)/dicyclohexylmethane-4,4''-diisocyanate(H12MDI) mixture, and 1,4-butane diol by solution polymerization. The physical properties of polyurethane elastomers at various feed ratios of HDI/H12MDI and from PTMG''s of various molecular weights were studied. As the HDI/H12MDI feed ratio and molecular weight of PTMG were increased, phase segregation into two domains of hard segment and soft segment was more evidently shown from thermal properties, infra-red spectroscopy, and tensile properties.

Poly(tetramethylene glycol) (PTMG). hexamethylene diisocyanate (HDI)/dicyclohexylmethane-4,4''-diisocyanate(H12MDI) 혼합물, 그리고 1,4-butane diol을 사용하여 폴리우레탄 탄성체를 용액 중합하여, 탄성체 내의 hard segment 성분인 HDI/H12MDI feed비와 soft segment인 PTMG의 분자량의 변화에 따른 물성의 변화를 조사하였다. HDI/H12MDI feed 비 값이 클수록, PTMG의 분자량이 클수록 hard segmend와 soft segment의 상분리 정도가 큼을 열적성질, 적외선 분광분석, 강신도 거동에서 관찰할 수 있었다.
