Abstract
Toxic waste materials are encapsulated by the method wherein the waste material in liquid or finely divided solid form is uniformly dispersed in a vinyl ester resin or an unsaturated polyester and the resin cured under conditions that the exotherm does not rise above the temperature at which the integrity of the encapsulating material is destroyed.
Claims19
A method for encapsulating liquid waste materials comprising uniformly dispersing said waste material into a fluid thermosettable resin composition of (1) a vinyl ester resin prepared by reacting about equivalent proportions of an unsaturated monocarboxylic acid and a polyepoxide resin, said vinyl ester resin containing ##STR2## linkage groups and terminal vinylidene groups attached to the ester end of said linkage or (2) an unsaturated polyester or (3) mixture thereof and a catalyst for curing said resin, and curing said composition under conditions that the exotherm is maintained below 100.degree.
