Water-vapor transport in poly(acrylic acid) (PAA), poly(N-vinyl-2-pyrrolidone) (PVPo), and their 2 : 1 interpolymer complex was measured between 30 and 50ΠC. It was found that the formation of interpolymer hydrogen bonding not only caused the T g of the complex to be higher than those of the individ

β¦ Synopsis
Sulfonated aromatic polyamide and different salts were synthesized. Water vapor diffusion in these polymers and X-ray diffraction of these polymers before and after water immersion were studied. The concentration dependence of the dihsivity is related to the morphological structure in the dry state and the change induced by absorbed water.

Two LC side-group poly(methacrylates) were synthesized, and their melt dynamics were compared with each other and a third, main-chain side-group combined LC polymer. A new route was developed for the synthesis of the poly(methacrylate) polymers which readily converts relatively inexpensive perdeuter
## Abstract Our previous work showed that drawing polyamide 66 (PA 66) fibers at room temperature does not change the degree of crystallinity, but only increases the molecular orientation. We therefore have used a series PA 66 fibers with different draw ratios to establish a direct correlation betw
