A lubricant composition having improved non-Newtonian viscometrics includes at least 85 weight percent of a base oil and 1 to 15 weight percent of a lubricant additive. The additive itself includes 10 to 80 weight percent of a diluent oil and 30 to 80 weight percent of a random co-polymeric viscosity index improver. The viscosity index improver is the free-radical polymerization product of at least 5 to 15 weight percent methyl methacrylate and 5 to 95 weight percent of a C-Calkyl (meth)acrylate. The additive is formed using a method that includes the step of providing the diluent oil, the methyl methacrylate, the C-Calkyl (meth)acrylate, and a free-radical initiator. The method also includes the steps of flowing the diluent oil into a reactor, flowing the methyl methacrylate and the C-Calkyl (meth)acrylate into the reactor independently from the free-radical initiator, and flowing the free-radical initiator into the reactor.

Lubricant composition having improved non-Newtonian viscometrics

A continuous process for preparing (meth)acrylates of C-alcohol mixtures by reaction of glacial (meth)acrylic acid with an isomer mixture of C-alcohols composed of 2-propylheptanol as the main isomer and at least one of the C-alcohols 2-propyl-4-methylhexanol, 2-propyl-5-methylhexanol, 2-isopropylheptanol, 2-isopropyl-4-methylhexanol, 2-isopropyl-5-methylhexanol and/or 2-propyl-4,4-dimethylpentanol, and the use of a diester of dicarboxylic acids which have been esterified with N-oxyl-containing compounds as polymerization inhibitors in such a process.

Preparation of (meth)acrylic esters of polyalkoxy-containing alcohols

The invention relates to a process for preparing (meth)acrylic esters by esterifying (meth)acrylic acid or transesterifying at least one (meth)acrylic ester with at least one compound comprising at least one OH group in the presence of a heterogeneous catalyst comprising at least one inorganic salt, wherein the esterification or transesterification is performed in the presence of 300 to 3000 ppm of water based on the total weight of the reaction mixture.

Process for preparing (meth)acrylic esters

A process for preparing (meth)acrylates of C-alcohol mixtures by reacting (meth)acrylic acid with a C-alcohol mixture in the presence of at least one acidic catalyst and of at least one polymerization inhibitor and in the presence of a solvent which, with water, forms an azeotrope in which the esterification is performed in a reactor with a circulation evaporator, the azeotrope is distilled off and condensed, and the condensate splits into an aqueous phase and an organic phase, wherein the C-alcohol mixture has a mean degree of branching (iso index) of 2.8 to 3.7.

The present invention relates to new coating materials for corrosion control.
