  • Patent number: 5801219
    Abstract: An acid-modified polyolefin is dispersed in water by adding a hydroxy-functional ester made from a polymeric acid and a monoepoxide having from 14 to 46 carbon atoms to the water. Said dispersion is substantially zero-VOC. When a composition of this invention is applied to the surface and cured by baking the article at an elevated temperature, a coating is obtained which improves the adherence of subsequent coatings to a polyolefinic article. A polyolefinic article is one having a surface comprising polypropylene or a polypropylene modified with rubber called a thermoplastic polyolefin (TPO).

  • Patent number: 5776362
    Abstract: A sludge dehydrating agent which is excellent in storage stability and prevented from becoming water-insoluble during storage and hence can be distributed in the market securely by solving the problem of the conventional dehydrating agents comprising amphoteric polymers that they undergo deterioration and become water-insoluble when stored for long, thus becoming substantially unusable. This dehydrating agent comprises a copolymer composed of cationic vinyl monomer units, vinylic carboxylic acid monomer units and nonionic vinyl monomer units and a salt of a group IIA metal of the periodic table. Preferable examples of the vinylic carboxylic acid monomer include acrylic, methacrylic and crotonic acids, while those of the nonionic vinyl monomer include acrylamide and methacrylamide. The metal salts usable herein include those of mineral acids and organic carboxylic acids, and preferable mineral acid salts include calcium chloride, magnesium chloride and magnesium sulfate.
