Curing Reaction of Water Soluble Copolymer of Acrylic Acid(Ester) Modified with C_(60)/C_(70)

In this paper,water soluble copolymers of acrylic acid/acetate and water soluble copolymers of acrylic acid/acetate modified with C60/C70 was used as main filming material respectively,and methylated melamine resin was used as curing agent.Then influence of the C60/C70 on reactivity of hydroxyl and carboxyl groups of the copolymers,as well as methoxyl methyl groups of the curing agent was studied.By means of testing to the differential scanning calorimetry(DSC) and solidifing degree of the solidifing reaction,results indicate that steric hindrance effect and variation of electronic distribution arising from the C60/C70 caused increase of curing temperatures of the copolymers.
