改良式聚胺基甲酸乙酯彈性體之研究(II)聚醚酯多元醇的合成及聚胺基甲酸乙脂的熱性質探討

THE STUDY OF SOME MODIFIED POLYURETHANES (II) : SYNTHESES OF POLYETHERESTER POLYOLS AND THE RELATED POLYURETHANES

摘要


聚醚酯多元醇的製備是由己二酸與不同低分子量之聚醚多元醇進行催化聚醚酯化反應:聚醚酯多元醇與甲苯二氰酸進行加成反應生成聚胺基甲酸乙酯預聚合物;最後再以MOCA固化並且探討聚胺基甲酸乙酯的製備與熱性質。

Polyether-ester polyols were synthesi6ed from the reactions of adipic acid with various low molecular weight polyether polyols via polycondensation with or without catalyst. Polyether-ester polyols were reacted with toluene diisocyanates , and polyurethahe prepolymers were resulted. These prepared polyurethane prepolymers were cured by MOCA and polyurethane elastomers were formed. The preparations and the thermal property of these prepared polyurethane elastomers were studied.
