Process for painting polypropylene

Chloride-free set accelerated cement compositions and methods of using the compositions for cementing conduits in well bores are provided. The compositions are comprised of hydraulic cement, sufficient water to form a pumpable slurry and a chloride-free set accelerator selected from trihydroxybenzoic acid, disodium dihydroxybenzenedisulfonate or derivatives of such compounds.

Chloride-free set accelerated cement compositions and methods

Chemically-modified, chlorinated, hydroxyimidized polyolefins having improved properties of solvent and/or humidity resistance and method for preparation thereof are disclosed. The novel materials prepared in accordance with the present invention are useful, for example, as primers for use with polymeric substrates.

Modified chlorinated polyolefins

Chemically-modified, chlorinated, hydroxyimidized polyolefins are used as stir-in additives to produce a paint having improved film appearance, adhesion and campatibility.

Cementing compositions having improved fluid loss capabilities for use in oil, gas, water and other well cementing operations are disclosed. Such compositions are comprised of water, hydraulic cement and a fluid-loss additive comprising a graft polymer comprised of a backbone of lignin, lignite, derivatized cellulose and various synthetic polymers selected from the group consisting of polyvinyl alcohol, polyethylene oxide, polypropylene oxide and polyethyleneimine. The grafted pendant groups comprise at least one member selected from the group of homopolymers, copolymers and terpolymers of 2-acrylamido-2-methylpropanesulfonic acid, acrylonitrile, N,N-dimethylacrylamide, acrylic acid, N,N-dialkylaminoethylmethacrylate and their salts. The backbone comprises from about 5 to about 95 percent by weight of the graft polymer, and the pendant groups can comprise from about 5 to about 95 percent by weight of the graft polymer.
