Cover: The graft polymerization of vinyl acetate (VAc) from poly(ethylene glycol) (PEG) was investigated by both experiments and modeling work. The graph on the left of the cover picture illustrates the graft copolymer molecular weight as determined by definitive calculation, GPC with PVAc or PEG calibration, and the model prediction. Using the correlated Arrhenius expression of the chain transfer constant to PEG(C PEG ), the graft copolymer molecular weights at various temperatures was predicted in the figure on the right.
