Multifunctional polyester-based poly

Poly (styrene), saturated polyahcycUc resins and terpene phenol reduce viscosity and impart high flow to the resulting composition. For this reason, the polymers added are sometimes addressed as flow promoters. The materials have some adverse effect as they reduce the heat deflee-tion temperature of the product and increase the flanunability. High flow polyphenylene ether resin compositions have been described." Dendrilie polymers based on polyesters with multifunctional hydroxy compounds offer the advantage to be effective in smaller amounts in comparison to common flow improvers." In addition, heterogeneous blends of PPE with PA have been introduced. 

Nuclear magnetic resonance (NMR) spectroscopy is one of the other basic methods for structural analysis. Aluri et al. [16] proposed a one-pot synthesis route to obtain two polymers of ABB for linear polyester and hyperbranched poly(ester-urethane)s based on multifunctional L-amino acid monomers using a temperature-selective melt...
