The number average molecular weight and strong acid end groups (SAG) of fractionated polymers were measured for the acrylonitrile-vinyl acetate copolymers (93:7 in weight), which were prepared by continuous polymerization in aqueous medium with the persulfate-bisulfiteion redox system. Average numbe

A novel polymerization method [Ruckenstein and Li, Polymer Bull., 37, 43 (1996)] -room temperature-initiated, self-heating polymerization-was applied to both bulk and concentrated emulsion copolymerization of acrylonitrile (AN) with vinyl acetate (VAc). A redox system was employed as an initiator, w
The enthalpies of fusion of two types of EVA copolymers containing 9 and 16% of vinyl acetate, respectively, were investigated by DSC. After melting, the samples were cooled down and held at 10, 15, 20, and 25°C for different periods of time from 15 min to 2.5 months (only at 20°C). The enthalpy of
## Abstract The bulk copolymerizations of acrylonitrile (AN) with vinyl acetate (VAc) initiated by azobisisobutyronitrile (AIBN) and the suspension copolymerization of AN with VAc and sodium methallylsulfonate (SMAS) in water with a Na~2~S~2~O~5~–Na~2~ClO~3~ redox initiator system at 65°C, were inv
