MECHANICALLY COMPATIBLE, POLYPHASE BLEND OF POLY(VINYL CHLORIDE), POLYOLEFIN, CHLORINATED POLYETHYLENE, AND GRAFT COPOLYMER OF POLYOLEFIN, AND RIGID FIBER REINFORCED COMPOSITE THEREOF ABSTRACT OF THE DISCLOSURE Shaped articles which have excellent solvent resist- ance and resistance to fatty acids are formed from a thermoplastic polyblend of poly(vinyl chloriae) (PVC), chlorinated polyethylene (CPE), polyolefin (PO), and a graft copolymer of a polyolefin (PO-G). The thermoplastic polyblend contains a PO and PO-G (PO/PO-G) as a first continuous single phase, PVC and CPE as the second and third dispersed phases, and the relative amounts of the components are chosen so that there is, at most, an equal amount by weight of PO and PO-G each of which may be present in an amount as high as 40 parts by weight when the PVC is present in an amount in the range from 40 to 70 parts, so as to provide a mechanically compatible poly- blend without miscibility or chemical compatibility. Further, a glass fiber reinforced (GFR) polyblend of PVC/CPE/PO/PO-G having a HDT of at least 95°C and suffic- ient thermoformability to form the desired article has excellent notched impact strength. In the GFR polyblend the fibers are preferably long, at least 3 mm, and from 10-20 microns in diameter. The high HDT is obtained prov- ided only if both co-compatibilizers and glass fibers are present in the reinforced composite.
