MULTILAYER COMPOSITE USEFUL AS A POLYMER ADDITIVE

摘要

A unique multilayer composite / "smart pellet" system was introduced as a method for producing reinforced matrix polymers with superior mechanical properties. Ethylene-octene copolymer / polysulfone and polypropylene / inorganic fiber were chosen as model systems with which to test this concept. The reinforcing agents were present in the multilayer composite and mixed with the matrix polymer in injection-molding. Mechanical properties of the resulting matrix polymer products were studied by performing tensile, flexural, and impact strength tests. The morphology behaviors of the multilayer composites and matrix polymer products were investigated by scanning electron microscopy, atomic force microscopy, and optical microscopy. In one experiment, the polysulfone layers resembled clay platelet morphology dispersed in a matrix polymer.
