<p>PURPOSE:To obtain the title composition which can give a laminate for electrical use excellent in the balance among heat resistance, impact resistance and low-temperature punching quality, essentially consisting of a specified partially esterified alcohol. CONSTITUTION:The title composition is obtained by mixing 2-10wt.% partially esterified alcohol (A) obtained by acylating part of the OH groups of a polyoxyalkylene polyalcohol with a polymerizable unsaturated carboxylic acid (e.g., maleic anhydride) and having an average MW of the alcohol moiety of 2,000-8,000 with a unsaturated segment (B) containing a polyoxyalkylene segment of an average MW of 600-6,000 in the skeleton, an unsaturated polyester (C) free of said polyoxyalkylene segment and 10-70wt.% crosslinking monomer (D). A plurality of bases impregnated with this composition are laminated, and the resin is cured to obtain an electrical laminate.</p> |
