Claims
- 1. A thermosetting resin composition which comprises
- (A) about 80 to about 30% by weight of a linear unsaturated polyester containing 10 to 100 mole percent of a dicyclopentadiene concentrate based on the moles of dicarboxylic acid or anhydride contained in said polyester,
- (B) about 20 to about 70% by weight of an unsaturated monomer mixture of a vinyl aromatic monomer and a dicyclopentadiene alkenoate wherein the range of dicyclopentadiene alkenoate in said mixture ranges from about 5 to about 90 weight percent.
- 2. The resin composition of claim 1 wherein the unsaturated polyester is prepared by the reaction under resin forming conditions of:
- (A) a glycol,
- (B) an olefinically unsaturated dicarboxylic acid or the anhydride thereof or mixtures thereof, and
- (C) 10 to 100 mole percent of a dicyclopentadiene concentrate based on the moles of dicarboxylic acid or anhydride.
- 3. The resin composition of claim 1 wherein the unsaturated polyester is prepared by the reaction of
- (A) a glycol,
- (B) an olefinically unsaturated dicarboxylic acid or the anhydride thereof or mixtures thereof,
- (C) a saturated dicarboxylic acid or the anhydride thereof or mixtures thereof or mixtures of (B) and (C), and
- (D) 10 to 100 mole percent of a dicyclopentadiene concentrate based on the moles of dicarboxylic acid or anhydride.
- 4. The resin composition of claim 1 wherein the dicyclopentadiene alkenoate is dicyclopentadiene acrylate.
- 5. A cured fibrous laminate made with the composition of claim 1.
- 6. A cured fibrous laminate made with the composition of claim 2.
- 7. A cured fibrous laminate made with the composition of claim 3.
- 8. A cured fibrous laminate made with the composition of claim 4.
