Manufacturing method of the blend which possesses the residual styrene monomer content ratio which is decreased, with the polystyrene and building a bridge type poly- vinyl pyrolidone is formed

摘要

This invention and regards the method of removing styrene residual monomer from the blend which contains non water soluble building a bridge type poly- vinyl pyrolidone from the polystyrene by processing with the water. This invention features that processing is done vis-a-vis the solid matter blend of form of particle. Selective figure It is not
