Polymeric materials and the preparation thereof

Abstract

Abstract POLYMERIC MATERIALS USEFUL IN LUBRICATING OIL COMPOSITIONS AS ANTIWEAR AND EXTREME PRESSURE ADDITIVES ARE PREPARED BY REACTING A COMPOUND (1) HAVING THE FORMULA: H-X-R-Y-H WHEREIN X AND Y ARE EACH SELECTED FROM THE GROUP CONSISTING OF SULFUR AND OXYGEN, AND R IS SELECTED FROM THE GROUP CONSISTING OF ALKYLENE, ARYLENE, CYCLOALKYLENE, AND CARBOXYLIC ACID ESTER DERIVATIVES THEREOF, SAID R CONTAINING BETWEEN ABOUT 2 AND ABOUT 60 CARBON ATOMS, WITH A HALOGEATED POLYMER (2), PREPARED BY REACTING OIL SOLUBLE POLYMER (3) HAVING A STAUDINGER MOLECULAR WEIGHT OF BETWEEN ABOUT 100 AND ABOUT 500,000 AND SELECTED FROM THE GROUP CONSISTING OF POLYMERS OF MONO-OLEFINS, POLYMERS OF DIOLEFINS, POLYMERS OF ETHYLENICALLY UNSATURATED MONOCARBOXYLIC ACID ESTERS, POLYMERS OF ESTERS OF ALPHA, BETA UNSATURATED CARBOXYLIC ACIDS, COPOLYMERS OF MONOOLEFINS WITH THE AFOREMENTIONED UNSATURATED ESTERS, POLYMERS OF VINYL ETHERS, AND POLYMERS OF VINYL ESTERS, WITH A HALOGENATING AGENT (4), THE REACTION OF (1) WITH (2) BEING CARRIED OUT AT A TEMPERATURE OF BETWEEN ABOUT 25% C. AND ABOUT 250%C. AND THE MOLE RATIO OF SAID REACTANTS (1) AND (2) BEING BETWEEN ABOUT 0.1:1.0 AND ABOUT 1:4:1.0.
