Polyesters containing bicyclo(2.2.1)hept-2-yl acrylate and methacrylate
Abstract
Abstract UNSATURATED POLYESTERS ARE REACTED WITH OR CROSSLINKED WITH BICYCLO(2.2.2)HEPT-2-YL ACRYLATE (BCHA) AND THE CORRESPONDING BICYLO(2.2.1)HEPT - 2 - YL METHACRYLATE (BCHMA) EITHER ALONE OR IN COMBINATION WITH OTHER VINYL MONOMERS COMMONLY USED FOR CROSSLINKING UNSATURATED POLYESTER RESINS. THE USE OF OR THE INCORPORATION OF BCHA OR BCHMA IN POLYESTER PREMIXES DRASTICALLY REDUCES THE LOSS OF VINYL MONOMER IN POLYESTER PREMIXES AND IMPROVES THE ULTRAVIOLET STABILITY WITHOUT DELETERIOUSLY AFFECTING THE RESIN PROPERTIES. EXAMPLES ARE GIVEN ILLUSTRATING THE REDUCTION OF VOLATILITY OF UNSATURATED POLYESTER PREMIXES WHICH EMPLOY STYRENE AND VINYLTOLUENE AS CROSSLINKING MONOMERS IN COMBINATION WITH EITHER BCHA OR BCHMA. THE RESINOUS PRODUCTS CONTAINING BCHA OR BCHMA ARE USEFUL AS MOLDING COMPOSITIONS, PROTECTIVE COATINGS, ADHESIVES AND LAMINATING RESINS.
