Abstract

The coalescence behavior of a 10/90 polydimethylsiloxane/polyisoprene blend was investigated using dynamic measurements in the linear viscoelastic region. It was found that blends with less than 1% of block copolymer displayed two relaxation mechanisms. A reduction in the shear rate caused a shift of the high frequency relaxation towards lower frequencies, which suggested the occurrence of coalescence. The blends with a concentration of block copolymers above 1% showed coalescence suppression.
