Abstract
PURPOSE: To obtain the titled molded product with excellent heat and weather resistance, by mixing and reacting a specified polyether polyol, a nonaromatic polyisocyanate, a crosslinking agent, a yellowing inhibitor, etc.
CONSTITUTION: The titled molded product composed of a polyurethane, containing 30W60wt% of hard segment, is obtained by mixing and reacting (A) 100pts.wt. of a polyether polyol of OH value 20W50, having 50% or more of terminal-added ethylene oxide and 2W8 functional groups, (B) a nonaromatic polyisocyanate (e.g., isophorone diisocyanate) of NCO index 90W130, having, on the average, 1.8 or less of 2-H (hydrogen bonded to a carbon atom bonded to a NCO group), (C) a crosslinking agent consisting of a low-molecular polyol of OH value ≥300, having at least two hydroxy groups, (D) a catalyst consisting of an organic metal salt (e.g., lead acetate), and (E) a yellowing inhibitor consisting of an antioxidant, an UV absorvent, etc.
