The percolationhyphen;tohyphen;cluster transition during spinodal decomposition of an offhyphen;critical polymer mixture. Observation by light scattering and optical microscopy

摘要

Direct observation of the percolationhyphen;tohyphen;cluster transition of an offhyphen;critical mixture of polybutadiene and polyisoprene was achieved by optical microscopy. According to optical evidence, the transition occurs in a slow and a fast step not revealed in parallel light scattering experiments.
