✦ Synopsis

The miscibility of nylon-6 with poly(4-vinylphenol) (PVPh) or poly(1-hydroxy-2,6-methylphenylene) (p-Cl-novolac) was studied with differential scanning calorimetry and small-angle X-ray scattering techniques. Both PVPh and p-Cl-novolac are miscible with nylon-6 at the molecular level. The presence of the phenolic polymers affects the crystallization of nylon-6 and suppresses its melting point. PVPh increases the long space order in crystalline nylon-6 because it increases the thickness of the amorphous layers. In contrast, a small quantity of p-Cl-novolac tends to decrease the long space order. It seems that p-Cl-novolac distributed in the amorphous regions introduces more order in these regions and makes the amorphous layers thinner.

A crystalline polymer, Nylon 6, was selectively blended with various amorphous polymers containing phenolic moieties. It was found that moisture absorption by the amide group in Nylon 6 could effectively be reduced by blending with p-Cl-novolac at ratios as low as 2 phr (part per hundred resin). Ble

## Abstract The phase behavior of blends containing chitosan with poly(vinyl‐alcohol) (PVA) and poly(2‐hidroxyethyl methacrylate) (P2HEM) was analyzed. Blends were obtained by casting from acetic acid solution (HAc) and 1,1,1,3,3,3 hexafluoro‐2‐propanol (HF2P) and studied by DSC, FT‐IR, and TGA. Th
