Environmentally benign adhesive was synthesized by dispersion copolymerization of
styrene(St) and butyl acrylate (BA) in an ethanol medium with benzoyl peroxide (BPO) as the initiator
and poly(vinylpyrrolidone) as the stabilizer in the presence of acrylic acid(AA) as the functional
monomer. The effect of the concentration of stabilizer, initiator and functional monomer on the
conversions, molecular weights and molecular weight distributions was investigated. The results
show that the conversions almost keep invariable with the increasing of stabilizer concentration, but
the molecular weights increase and molecular weight distributions decrease. Conversions increase
with the increasing of initiator concentration, but the molecular weights and molecular weight
distributions decrease. However with the increasing of functional monomer concentration,
conversions and molecular weight distributions increase but the molecular weights decrease.
