摘      要：Polymerization of N-Octadecylmaleimide was studied using rare earth coordination catalysts in *** dependence of polymerization on molar ratio of catalyst components,different rare earth elements,catalyst concentration,monomer concentration,polymerization time and polymerization temperature was investigated in *** results showed that the rare earth catalysts were favorable catalysts for the polymerization of N-Octadecylmaleimide.A suitable condition for the polymerization was [La(P507)3]= 1×10-2?mol·L-1;（[Al（i-Bu）3]）=8.0×(10-2?mol·L-1);[NODMI]=5.0×(10-1?mol·L-1);60℃;6?*** of the polymer obtained showed that polymerization of N-Octadecylmaleimide proceeded via opening the double bond in the monomer *** heat-resistant property of the polymer was investigated *** polymer showed excellent thermal *** thermal decomposition of the polymer proceeded via a one-step reaction and no substantial weight loss was observed below 350℃.The initial decomposition temperature(Tini) was 360℃,the maximum decomposition temperature(Tmax) was 441℃,and the residual weight at 500℃ was about（3.4?wt%）.
