Abstract

Summary: Nylon‐6/Na^+^‐montmorillonite (MMT) nanocomposites (NNNs) are synthesized by a hydrolyzed ring‐opening polymerization. At a loading of only 2 wt.‐% MMT, the tensile modulus, the flexural modulus, and the heat distortion temperature of the NNNs exhibit increases of nearly 20%, 60%, and 63 °C, respectively. Compared with that of neat nylon‐6, the temperature of the main α‐relaxation (T~α~) of the NNNs is shifted 3.6 °C toward higher temperatures and two β‐relaxation peaks are observed. Another interesting phenomenon is that there is a new melting peak (at about 206 °C) for the NNNs.

## Abstract Epoxidized soybean oil (ESO) was converted to a polysoap (PESO) via a two‐step synthetic procedure of catalytic ring‐opening polymerization, followed by hydrolysis (HPESO) with a base. Various molecular weights of PESO and HPESO were prepared by varying the reaction temperature and/or c

Polyamide 6-montmorillonites membranes have been prepared and studied for a large range of clay content (from 0 to 18 wt.%). The barrier properties of these systems have been determined for different diffusing molecules varying by their kinetic diameter and their interaction capacity. The relative p
