Abstract
Disclosed are a vinyl chloride-based polymer-polyurethane composite comprising vinyl chloride-based polymer (1), polyurethane, plasticizer (4), metal salt of higher fatty acid (6) and hydrocarbon-based lubricant (7), the metal of metal salt of higher fatty acid being at least one element selected from a group consisting of magnesium, zinc and lead, which have low hardness and excellent hydrolysis resistance, compression set characteristic and profile extrusion moldability, and a method of producing vinyl chloride-based polymer-polyurethane composite which is produced by means of of heating, melting and mixing not less than 200 parts by weight to not more than 800 parts by weight of polymer polyol (2), isocyanate compound (3) with three or more isocyanate groups in amount of the molar ratio of isocyanate group in isocyanate compound (3) to hydroxyl group in polymer polyol (2) being not less than 0.3 to not more than 0.8, not less than 10 parts by weight to not more than 300 parts by weight of plasticizer (4) and urethanating reaction catalyst (5) to 100 parts by weight of vinyl chloride-based polymer (1) under shear force.
