Synthesis, Characterizationand Glass-reinforced Composites of Trimethylolmelamine-phenol Resins

摘要

Trimethylolmelamine (TMM) has been prepared and characterized. The TMM condensed with phenol in the presence of alkali catalyst at the varying ratios of TMM: Phenol, viz. 1:1, 1:1.5 and 1:2. The resultant triazine ring containing resins (TMMP) were characterized by elemental analyses, IR spectral studies and thermogravimetry. The isothermal curing study of TMMP resin with hexam4ethylenetertramine (HMTA) was also carried out. finally, the glass-reinforced composites based on TMMP-HMTA system have also been prepared and characterized for synergetic property combination of both MF and PF.
