摘要

The present Invention refers to a Composition of polimezcla in POLYPHASE, thermoformable, which has several First, second and Third stages but with no miscibility, Mechanical compatibility.The polimezcla is characterized essentially consists of (i) 10 to 40 parts by weight of olefin Polymer (OP)(ii) 20 but less than 40 parts of a Graft Copolymer of olefin Polymer (OP (g),The Graft Copolymer has a fusion rate in the range of about 2 to 40 grams / 10 minutes, under the condition of the STM test G D 1238 - 73(i) and (ii) form the first phase; (iii) of 40 to 70 parts of Poly (Vinyl Chloride) (PVC), which is the second phase and (iv) of 10 to 30 portions of chlorinated polyethylene (CPE),At least 5 Parts which has a Content of C1 sufficient to maintain substantially its crystallinity, forming the third phase; the amount of PVC, po and po G,Are chosen so that there are more po and PVC as much an equal amount by weight of po and po G, to provide the first phase in a continuous mixture substantially RIGID PVC and CPEThe dispersed phases.
