The present invention relates to a novel method of using industrial dicyclopentadiene of purity of 75 percent to 85 percent to prepare modified unsaturated polyester resin. In the preparation of the resin, the industrial dicyclopentadiene separated from the saturated or unsaturated dicarbonic acid or acidic anhydride and the distilled part of mixed C5 is used as the raw material. After hydrolysis and addition reaction, the diol or polyol of appropriate amount is added. The polymerization and dehydration reaction is done with the influence of acidic catalyst. When the mixture is condensed to the designated acid value, the inhibitor and cross-linking monomer of appropriate amount are added and then stirred to prepare the product. The present invention has the advantage that the cost of resin is lower than the common type unsaturated resin.
