NEW APPROACH TO UTILIZATION OF ROSIN IN SYNTHESIS OF UNSATURATED POLYESTER RESIN |
| |
| Abstract: | Unsaturated Polyester of dimeric abientic acid type could be obtained by using dimeric abientic acid instead of o-phthalic anhydride. The obtained polyester was compatible with monomers at any ratios, and the cured product possessed good water resistance, good chemical resistance, good electric insulation and a moderate exothermic peak. This polyester was suitable for use as casting and potting compounds. |
