Novel polyols, useful in, for example, reaction injection molding, high resiliency foams and the preparation of polymer/polyols, characterized by the following formula:
wherein A and A', which may be the same or different, are connective atoms - carbon, oxygen or combinations thereof with hydrogen atoms or the like satisfying the valences; B is nitrogen (N) or CR, R being hydrogen, alkyl, aryl or the like; Q is 0, CH20, C2H4O, C3H6O, or C4H8O; D is an oxyalkylene or
X and X'. which mav be the same or different, are OH, NH2 or H; Z is OH; n and dare integers of 0 to 10 and the sum of and d does not exceed 10; s is 0 or 1, and m is an integer of at least about 16. with the proviso that when B is N and either n or d is zero, X and X' are otherthan H, provide processing advantages and are highly compatible with low molecular weight extenders such as ethylene glycol.
新型多元醇,可用于例如反应注射成型、高回弹性泡沫塑料和制备聚合物/多元醇,其特征为下式:
其中 A 和 A'(可以相同或不同)是连接原子--碳、氧或其组合,氢原子或类似原子满足价位;B 是氮(N)或 CR,R 是氢、烷基、芳基或类似原子;Q 是 0、CH20、
C2H4O、
C3H6O 或
C4H8O;D 是氧亚烷基或
X和X'可以相同或不同,是OH、NH2或H;Z是OH;n和敢是0至10的整数,且和d之和不超过10;s是0或1,且m是至少约16的整数。但当B是N且n或d为0时,X和X'是除H以外的其他物质,具有加工优势,且与低分子量扩展剂如
乙二醇高度兼容。
