    摘要： Anaerobic adhesive compositions, the reaction products of which demonstrate improved cure speed and bond strength are disclosed. A high percentage of ultimate bond strength is reached within the first hour of room temperature cure. Higher ultimate bond strengths as compared to conventional compositions are achieved. The anaerobic adhesive compositions incorporate an adhesion promoter which contributes to these properties.

    摘要： A method of treating wastewater including a heat-curable (meth)acrylic monomer-containing composition, at temperature below that necessary to effect heat-curing of the composition. The wastewater may be produced by aqueous washing of porous parts impregnated with a sealant composition containing such monomer. The monomer-containing wastewater is (1) adjusted in pH to a value in the range of from about 8 to about 10, and (2) contacted with an effective amount of a reducing agent which is polymerizingly effective for the monomer, to yield corresponding polymer from the monomer. The wastewater is mixed with a cationic flocculating agent in sufficient quantity to flocculate the polymer in the wastewater, and the resulting wastewater is physically separated to recover a monomer- and polymer-reduced wastewater effluent which may be discharged to receiving waters.
