By using 30/70 polyethersulfone/NMP ( N-methyl-2-pyrrolidone) solutions as an example, we have determined the role of air-gap distance on nascent fiber morphology, performance, and thermal properties. An increase in air-gap distance results in a hollow fiber with a less layer of fingerlike voids and

## Abstract A series of allylβfunctional novolac (AN) resins with various allylation degree, from 32.4 to 114.6%, were synthesized and blended reactively with 4,4β²βbismaleimide biphenyl methane (BMI) at a weight ratio of 2.50 : 1 to get BMIβmodified and allylβfunctional novolac (BMAN) resins. Struc
Studies have been undertaken to investigate the effect of sugars on the thermal and rheological properties of sago starch. Sugars were found to increase the gelatinization temperature T(gel), and gelatinization enthalpy DeltaH. T(gel) and DeltaH increased in the following order: control (water alone
Films of polypropylene, co-extruded polypropylene/nylon/polypropylene and clear polyester laminated to polypropylene have been subjected to thermal treatment over a temperature range of 118-120ΠC. The mechanical, optical, thermal and chemical resistance of these films have been studied before and af
