Synthesis and rheological behavior of cross-linkable poly[N-(methacryl-2-ethyl)-N′-(3-amino(1,2,4-triazole-2-yl))urea-co-methyl methacrylate]

A copolymer poly[N-(methacryl-2-ethyl)-N′-(3-amino(1,2,4-triazole-2-yl) urea)-co-methyl methacrylate] (1) with a low Mn value of about 1300 was prepared via free radical polymerization from the corresponding monomers N-methacrylethyl-N′-triazoyl urea (2) and methyl methacrylate (3). The complex viscosity of a solution of i in N-methyl pyrrolidone decreases with increasing temperature up to 32 °C at the beginning and then passes a minimum at 38 °C. At higher temperatures of about 53 °C, it decreases again. DSC measurements of this solution indicates phase transitions because of two endothermic signals from 32 to 44 °C and from 53 to 74 °C. Furthermore, the copolymer 1 starts to cross-link rapidly above 130 °C. The mechanism of this cross-linking reaction is discussed with respect to a back-formation of isocyanate intermediate that reacts with nucleophiles.
