SYNTHESIS AND CHARACTERIZATION OF EPOXY-MODIFIED WATERBORNE UNSATURATED POLYESTER AND THEIR USE IN FIBER SIZING AGENTS
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
Epoxy-Modified Waterborne unsaturated Polyester (WUP) were synthesized by phthalic anhydride, dipropylene glycol, maleic anhydride, epoxy resin, methyl tetrahydro phthalic anhydride and triethylamine. The chemical structures of the WUP products were characterized by Fourier transform infrared spectroscopy（FT-IR）. The thermal properties of the WUP were examined by thermogravimetric analysis (TGA). TGA showed that the WUP had good thermal stability. The particle size of WUP sizing agents was characterized by Laser Particle Size Analyzer. The emulsion morphology and aggregation state were evaluated by scanning electron microscopy (SEM). The SEM confirmed that the particle size of WUP sizing agents was Nano-sized and monodisperse microspheres. The excellent properties of WUP confer it with potential applications as sizing agents in glass fiber and carbon fiber.
