✦ Synopsis

Samples of Nylon G/poly(propylene oxide), with poly(propy1ene oxide) (PPO) content varying up to 35%, have been examined using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and nuclear magnetic resonance (NMR) carbon-13 at solidstate. Carbon-13 spectra were measured by cross-polarization (CP), magic angle spinning (MAS), and high-power hydrogen decoupling (HPHD). The variation contact time experiment and MAS technique were also determined. The data are discussed in terms of compatibility and plasticization of the samples.

Two types of blends containing polyamide 6 and poly(propylene oxide) (PPO) were prepared. One of them was mixed with polycarbonate (PC) in a Brabender mixer. The other one was prepared in solution with the block copolymer as the interfacial agent. The blends were analyzed by 13 C nuclear magnetic re
