Abstract
PURPOSE: The titled composition, having low shrinkage, adhesion, electrical insulating properties, sound absorbing properties and resistance to thermal deterioration, and obtained by incorporating a specific modified unsaturated polyester containing cyclopentadiene polymer, etc. with a vinyl monomer, an inorganic filler, etc.
CONSTITUTION: A composition prepared by incorporating (A) a modified unsaturated polyester consisting of (i) an unsaturated polyester modified with an aromatic hydrocarbon resin, e.g. xylene-formaldehyde resin, containing oxygen, (ii) a cyclopentadiene polymer expressed by the formula [n is an integer 1W15; X is HOOC- R-COO-, HO-R-O-(R is 1W10C alkylene or alkyl ether, aromatic or alicyclic ring)] and (iii) a mixed acid of an unsaturated fatty acid with a saturated fatty acid with (B) a vinyl monomer, (C) an inorganic filler and (D) a catalyst. The mixing weight ratio of (i)/(ii)/(III) is 10W80/5W60/5W70, and that of (A)/(B) is 100/ 30W100/50. Preferably, the weight ratio of (C)/(A) is 1/100W3/100, and that of (D)/(A) is 200/100W700/100.
