Conference paper


Branching effect on shear and elongational flow properties is an important topic for polymer industry as well as for polymer science. Randomly branched polystyrenes (RBPS) were synthesized by copolymerization of styrene and divinylbenzene (DVB), and the melt rheological properties of different homologous series were investigated both in the linear and nonlinear viscoelastic response region.
