PREPARATION OF COMPOSITE-PARTICLES COMPOSED OF WASTE POLYMER AND PAPER FIBER BY CHEMICAL CRUSH METHOD

Composite particles composed of waste polymer and waste paper fibers w ere prepared by a chemical crushing method. Newspaper was used as pape r fiber. Polystyrene beads, which were prepared by suspension polymeri zation, were adopted as the waste polymer. In the experiment, in order to adjust the affinity for the polymer solution, paper fibers were pr etreated using a few treatment agents. It is found that the mechanical strength of the composite particles increases by addition of fibers. Furthermore, it is found that there is an optimum concentration for ea ch treatment agent.
