Protein and Acrylonitrile Copolymerized Fiber “Chinon”

A photocrosslinkable melt processible acrylonitrile terpolymer as carbon fiber precursor

A novel photocrosslinkable and melt processible terpolymer precursor for carbon fiber has been successfully synthesized and characterized. The terpolymer was synthesized by an efficient emulsion polymerization route and has a typical composition of acrylonitrile/methyl acrylate/acryloyl benzophenone in the mole ratio, 85/14/1. It has been characterized by FTIR, NMR, intrinsic viscosity and GPC ...

mechanical and morphological properties of short nylon fiber reinforced acrylonitrile-butadiene rubber composites

acrylonitrile butadiene rubber (nbr) composites are prepared from waste nylon 66 short fiber using a two-roll mill mixer. the effects of fiber content and bonding agent on the mechanical and morphological properties of the composites are studied. the curing characteristics of the composites have been studied by using cure rheometer. the cure and scorch time of the composites decrease while cure...

Modification of fiber properties through grafting of acrylonitrile to rayon by chemical and radiation methods

Fibrous properties of rayon has been modified through synthesis of graft copolymers of rayon with acrylonitrile (AN) by chemical method using ceric ammonium nitrate (CAN/HNO3) as a redox initiator and gamma radiation mutual method. Percentage of grafting (Pg) was determined as a function of initiator concentration, monomer concentration, irradiation dose, temperature, time of reaction and the a...

Synthesis and Thermal Properties of Acrylonitrile/Butyl Acrylate/Fumaronitrile and Acrylonitrile/Ethyl Hexyl Acrylate/Fumaronitrile Terpolymers as a Potential Precursor for Carbon Fiber

A synthesis of acrylonitrile (AN)/butyl acrylate (BA)/fumaronitrile (FN) and AN/EHA (ethyl hexyl acrylate)/FN terpolymers was carried out by redox polymerization using sodium bisulfite (SBS) and potassium persulphate (KPS) as initiator at 40 °C. The effect of comonomers, BA and EHA and termonomer, FN on the glass transition temperature (Tg) and stabilization temperature was studied using Differ...
