  • Oil-soluble reaction products of (A) a high molecular weight olefin polymer, acetonitrile, and chlorine with (B) an amine, and lubricant compositions containing the same
    Patent number: 3953349
    Abstract: Novel addition agents for lubricants, are obtained by reacting a high molecular weight olefin polymer, having an average molecular weight of at least about 600, with acetonitrile and a halogen, for example chlorine, in the presence of a catalyst, such as iodine, for example, to form the intermediate (A) which is reacted with a primary or secondary amine.

  • Polymerization of acrylamide in the presence of water-soluble nitrogen compounds
    Patent number: 3951934
    Abstract: A process for producing a substantially nonionic water-soluble acrylamide polymer produced without the occurence of hydrolysis of the acrylamide polymer by heating when the reaction system undergoes an unavoidable heat aging such as due to heat of polymerization comprising polymerizing a comparatively high concentration aqueous solution of acrylamide in the presence of a specific water-soluble nitrogen compound.

  • Fluoroelastomer composition
    Patent number: 3951913
    Abstract: A fluoroelastomer composition which contains (a) a fluoroelastomer, (b) at least one metal compound selected from the group consisting of bivalent metal oxide, bivalent metal hydroxide and mixture of bivalent metal oxide or metal hydroxide with metal salt of weak acid, (c) an aromatic polyhydroxy compound, (d) a quaternary ammonium compound of 8-alkyl- or 8-aralkyl-1,8-diaza-bicyclo[5.4.0]-7-undecenium, and (e) 1,8-diaza-bicyclo[5.4.0]-7-undecene in an amount of not more than 0.07 part by weight per 100 parts by weight of fluoroelaster, provides a fluoro-rubber having a low compression set and an excellent elastic property. The fluoroelastomer composition can be handled and processed with safety, and yet can be cured with an appropriate induction time and a good cure rate, and has excellent storage properties.
