【摘要】 讨论了多元醇与环氧丙烷（ＰＯ）及环氧乙烷（ＥＯ）共聚物的支链数、支链的分子量、ＰＯ与ＥＯ的摩尔比、分子间的交联对ＣＯＭ燃料流动性的影响。当稳定剂分子的支链子均分子量在 ５ ０００以上、 ＰＯ与 ＥＯ的摩尔比接近２、分子链间进行适当交联，支链数目又较多时，ＣＯＭ燃料的流动性较好。三聚氰胺六羟甲基在ｐＨ为４．５时缩合１０ｍｉｎ，与ＰＯ及ＥＯ加成后再加入２倍于它的摩尔数的 ＴＤＩ进行交联，用它配制的 ＣＯＭ的含碳量最高可达６６％。更多还原

【Abstract】 Effects of number, molecular weight, molar ratio of PO and EO, crosslink density of branched chain on fluidity are discussed.when PO:EO is equal to 2,molecular weight approach 5 000, branched chain is many and having suitable crosslink density fluidity of COM made up by this stabilizing agent is the best,when making hexahydroxymethyl melamine condensation by 10 min in pH=4.5 and copolymerization with PO and EO,copolymers are cross-linked by TDI,mole of which is 2 times of copolymers,the greatest content of coal is 66%.更多还原
