摘要：经两步法合成了螺环原碳酸酯膨胀单体3,9-二羟甲基-3,9-二乙基-1,5,7,11-四氧杂螺环[5.5]十一烷,用2,4-甲苯二异氰酸酯(TDI)与聚丙二醇(PPG)合成端异氰酸酯基的聚氨酯预聚物,并使二者共聚制备新型膨胀单体预聚物。采用红外光谱、核磁共振、元素分析对产物进行了表征。将该膨胀单体预聚物加入到N,N'-(4,4'-二苯甲烷)双马来酰亚胺(BDM)/3,3'-二烯丙基-4,4'-二苯丙烷(DABPA)共混体系中,减少了BMI/DABPA体系固化过程中的体积收缩。
A spiro orthocarbonate expansion monomer 3,9-diethyl-3,9-dihydroxymethyl-1,5,7,11 -tetraoxaspiro [ 5.5 ] undecane was synthesized by two steps, and then expansion monomer prepolymer was prepared by copoly- merization of expansion monomer and the polyurethane prepolymer which was prepared with 2,4-toluene diisocyanate and propylene glycol. The pruducter was characterized by FT-IR spectra, X HNMR and element analysis. With the in- troduction of the expansion monomer prepolymer into the blends of N, N＇-4,4＇-diphenylmethane-bismaleimide （BMI）/O, O＇-diallyl bisphenol A（DABPA） ,the volume shrinkage of the BMI/DABPA system was reduced.
