Effect of Brominated Flame Retardants on the Properties of Acrylonitrile /Vinyl Acetate Copolymer FibersDepartment of Textile Engineering, National Taiwan Institute of Technology, Taipei, Taiwan, Republic of China
Department of Textile Engineering, National Taiwan Institute of Technology, Taipei, Taiwan, Republic of China Two brominated flame-retardant additives, Great Lakes CD-75P (hexabro-mocyc lododecane) and Great Lakes PDBS (a polymer of dibromostyrene ), are introduced into acrylonitrile/vinyl acetate (AN/VA) fibers, and their effects on the fibers' thermal and mechanical properties, morphology, and flammability are investigated. Because the additives influence the viscosity of AN/ VA solution dope, the influence of spinneret diameter on spinning the modified AN/VA fibers is also studied. The results show that the both additives can reduce flammability with little effect on tensile strength but large effect on the breaking elongation.
