Abstract
Set retarders of copolymers of at least one polymerizable ethylenically unsaturated monomer and at least one alkoxylated monomer are capable of delaying the hardening of a cementitious slurry when introduced into a subterranean formation until a downhole temperature greater than or equal to 500° F. is obtained, even in the absence of an intensifier.
