Abstract
A modified sulfur cement comprising the polymeric reaction product of elemental sulfur and a cyclopentadiene oligomer containing reactant. Cement compositions can be formulated by blending an aggregate material with the modified sulfur cement.
Claims7
A modified sulfur cement comprising:
- the polymeric reaction product of elemental sulfur and from 20 to 40 wt. % of a modifier being the combination of dicyclopentadiene and an oligomeric mixture comprising at least trimers of cyclopentadiene, said sulfur cement having a softening point of no more than 116.degree. F.
A method of preparing a modified sulfur cement comprising:
- reacting sulfur with from 20 to 40 wt. % of a modifier being the combination of dicyclopentadiene and an oligomeric mixture comprising at least trimers of cyclopentadiene said sulfur cement product having a softening point of no more than 116.degree. F.
