Abstract: Reaction mixtures for forming curable epoxy resin compositions comprise an epoxy resin, a monoethylenically unsaturated monomer capable of forming polyacrylate rubber, a chain transfer agent to allow for higher levels of rubber in the curable epoxy resin without undesired vixcosity increase and/or gellation, and a monomer soluble initiator. Optional ingredients include a crosslinking agent for the rubber-forming monomer, a grafting agent for rubber and epoxy resin, and an epoxy curing agent, preferably having activation conditions which are not satisfied when the initiator is activated. Heating the reaction mixture gives epoxy resin compositions containing polyacrylate rubber, the latter being optionally crosslinked and/or grafted to the epoxy resin. Activation of the curing agent, e.g., by heating, when such curing agent is present, yields cured adhesive compositions.

Abstract: Sulfur dioxide (S0 2 ) is absorbed from waste gases by absorbing S0 2 in an aqueous absorbent comprising soluble sulfite in an absorber: stripping the S0 2 from the absorbent: absorbing the stripped S0 2 in a separate absorbent for the S0 2 ; and reacting the thus absorbed S0 2 in a liquid Claus reactor forming sulfur. In a preferred embodiment, the gas from the stripping step is subjected to a condensation step in a heat exchanger boiler where steam ingoing to the stripper is generated.
