Abstract��
The structure of macromonomer (MM)synthesized by reacting polyether polyol with maleic anhydride(MA) was characterized with GPC,(()~1H)-NMR and double-bond titration.The results indicated that,besides the reaction of polyether with MA,the procedure also involved many chemical reactions including double-bond isomerization and double-bond addition.For double-bond addition,the molecular weight of MM increased,and the content of double-bond became less.Reaction temperature palyed an important role on the properities of MM which,including the content of double-bond,double-bond isomerization and molecular weight,resulted in the stability.At 120 ��,the stability of MM was best.
