This article addresses the effect of thermal aging on unreinforced and glassreinforced recycled polyamide 66. As an accelerated test, injection-molded test bars were aged at 110, 140, and 170ΠC for up to 4000 h in air to simulate service life. FTIR spectroscopy demonstrated that the oxidative degrad
The oxidation of serine (HORC0,H) by acid permanganate was investigated both in the absence and presence of sodium dodecyl sulfate (SDS). It has been observed that the presence of surfactant enhanced the reaction rate. The reaction is first order with respect to [Serine] and [MnO,-1. The reaction is
## Abstract A series of composites of PPO/PA 6 with improved toughness were synthesized by using Ξ΅βcaprolactam as a reactive solvent. Inserting minor PPO macromolecules (1β3 wt %) into PA 6 matrix obviously reduced the crystallinity of PA6. Two crystallization temperatures were found when 6 wt % PP
