Rheological Control with Block Copolymers

Nanophase separation of block copolymer melts introduces interesting rheological behavior. For example, the transient elongational viscosity behavior of a triblock copolymer of styrene and olefins was found to be strongly dependent on the initial orientation of the cylindrical domains [103]. [Pg.714]

While conventional processing of polymers involves melting, block copolymers such as PS-fo-PnBA display melt-like behavior simply on application of pressure at room temperature this is due to pressure-induced miscibility of the blocks (baroplastics [104]). [Pg.714]

Precipitation and gelation of long-chain paraffins in waxy crude oils hinders their fiow and hence their recovery and processing. Flow characteristics can be im- [Pg.714]
