A series of new poly(vinyl alcohol)‐g‐methyl methacrylate/N‐substituted maleimide graft terpolymers were prepared by reacting the residual anhydride groups on the poly(vinyl alcohol)‐g‐methyl methacrylate/maleic anhydride with the appropriate N‐substituted amines through the poly(vinyl alcohol)‐g‐methyl methacrylate/N‐substituted maleamic acid intermediate. Here, the N‐substituted amines were N‐benzyl, N‐butyl, N‐octyl, N‐dodecyl and N‐ethylol amines. The compositions and the proposed structure of the resultants were determined by elemental and infrared analyses. The water content, thermal and mechanical properties of the new poly(vinylalcohol) graft terpolymers were also investigated.
