Pour point improving additives for mineral oils

Multirange lubricating oils having high shear stability comprising paraffinic oils as their base and containing, as an additive improving the viscosity index, a mixture of at least two different polymer species, each of said polymer species being composed of monomers selected from the group consisting of

Shear stable multirange oils having an improved viscosity index

What are disclosed are concentrated emulsions of an olefin copolymer in a liquid carrier medium which does not dissolve the copolymer and, as an emulsifier, a graft or block copolymer of the formula

Concentrated emulsions of olefin copolymers

A process for the suspension polymerization of ethylenically unsaturated monomers -- particularly for the preparation of water-soluble polymers -- wherein a liquid monomer phase is polymerized while suspended in a liquid organic suspending medium in the presence of a macromolecular stabilizing or suspending agent having a macromolecular portion or portions solvated by the liquid monomer phase and another macromolecular portion or portions solvated by the liquid organic suspending medium. Water-soluble suspension polymers, preparable by this process, comprising quaternization products or salts of dialkylaminoalkyl esters or of dialkylaminoalkyl amides of acrylic acid or of methacrylic acid.
