Abstract: A method for forming a grout composition from multiple components. A first component is mixed in pre-measured amounts along with water in a first mixing tank. A first catalyst is added in pre-measured quantities to the first mixing tank. A second catalyst is mixed in pre-determined quantities with water in a second mixing tank. The aqueous solutions in the first and second mixing tanks are combined to cause a polymerization-cross-linking reaction of the first component which results in gellation of the first component.

Abstract: An improved process for producing an aqueous polymer emulsion is provided wherein a radically polymerizable unsaturated monomer is polymerized in an aqueous medium in the presence of a water-soluble copolymer. The water-soluble copolymer is derived from a combination of (a) a nitrogen-containing ethylenically unsaturated compound with (b-1) an unsaturated carboxylic acid or its salt and/or (b-2) an ethylenically unsaturated sulfonic acid or its salt.

Abstract: Unsaturated polyesters resins are prepared having improved flexural strength, corrosion resistance, and heat resistance by incorporating into the resins a dicyclopentadiene ether compound having one of the formulas ##STR1## where R.sub.o =dicyclopentadienyln=0-2R.sub.1 =--C.sub.x H.sub.2x --(O--C.sub.x H.sub.2x).sub.zx=1-4z=0-2R.sub.2 =--OH, --O--R.sub.oR.sub.3 =R.sub.2, --O--CH.sub.2 --CH(R.sub.2)--CH.sub.2 --R.sub.2R.sub.4 =--C.sub.y H.sub.2y --(O--C.sub.y H.sub.2y).sub.wy=2-4w=0-2R.sub.5 =R.sub.2, --CH.sub.2 --OH, --CH.sub.2 --O--R.sub.o, --CH.sub.3, or --HR.sub.6 =--OH, --CH.sub.2 --OH, --CH.sub.2 --O--R.sub.o, --O--R.sub.o, --(O--C.sub.y H.sub.2y).sub.w --OH; and whereinR.sub.2, R.sub.3, R.sub.5 and R.sub.6 are chosen so that each compound has at least one hydroxyl group, with the proviso that the combined moles of (D) and (E) are in the range of 0.30 to 2.2 moles per mole of (A).

Abstract: Polymerization method utilizing a three-phase system: water-in-oil-in-water or oil-in-water-in-oil comprising the steps (a) adding the monomer material to be polymerized into the innermost water or oil phase; (b) adding, with mechanical agitation, the product of Step a to the middle oil or water phase, said phase containing appropriate surfactant, whereby an emulsion is formed; (c) adding, with mechanical agitation, the emulsion product of Step b to the outermost water or oil phase, said phase containing appropriate surfactant, wherein polymerization proceeds in the innermost water or oil phase until complete.
