• Description:
  Polymeric sulfur reaction products with cyclopentadiene oligomer-dicyclopentadiene mixtures are prepared to give sulfur modified with at least 37 wt pct dienes and useful as cements with excellent strength and freeze-thaw stability and improved workability and setting up to rigid products. Thus , a building material prepared from S 21, cyclopentadiene oligomer 1.75, and dicyclopentadiene 3.75, heated 24 h at 130 deg C and blended with limestone 79 wt pct had compressive, tensile, and flexural strengths 8,170, 1,020, and 1,570 psi, respectively.
