Abstract: PROBLEM TO BE SOLVED: To obtain an ester of carboxyl-containing mixture polymer capable of providing a functional fluid relatively high in the level of mixture polymer with a good low-temperature characteristic, and to obtain a carboxyl-containing mixture polymer as an intermediate therefor. SOLUTION: This nitrogen-containing ester is of a carboxyl-containing mixture polymer derived from a vinyl aromatic monomer and α,β-unsaturated carboxylic acid or any anhydrate or ester thereof, wherein the mixture polymer has an intrinsic viscosity of 0.05 to 0.30 and the nitrogen-containing ester has the following pendant polar groups: (A) a carboxylic acid ester group having at least 8 aliphatic carbon atoms in the alkyl site of the ester group; and (B) a carbonylamino group derived from an amino compound having a primary or secondary amino group.

Abstract: PROBLEM TO BE SOLVED: To obtain an additive concentrate, capable of imparting excellent low-temperature characteristics and improving properties of viscosity index and useful as a viscosity improver, etc., by including a specific organic diluent and a specified ester in a specific proportion therein. SOLUTION: This additive concentrate comprises (A) 5-95wt.% organic diluent such as a naphthenic oil or a synthetic oil and (B) 95-5wt.% ester derived from a carboxy-containing interpolymer having 0.05-0.35 reduced specific viscosity. The interpolymer is derived from two or more monomers of components (i) and (ii). (i) either one of the monomers is one or more of a 2-30C aliphatic olefin and a vinyl aromatic monomer and (ii) the other of the monomers is one or more α,β-unsaturated acylating agents. The ester has 20-70mol% of 12-19C ester groups (based on the number of mol of carboxyl groups in the interpolymer) and 80-30mol% of 8-11C ester groups (based on the number of mol of the carboxyl groups in the interpolymer), derived from carboxy groups of the interpolymer and present in the polymeric structure thereof.

Abstract: Nitrogen-containing esters of a carboxy-containing interpolymer, wherein the interpolymer has an inherent viscosity ranging from about 0.05 to 0.30 are disclosed. The esters are useful as additives in functional fluids including transmission fluids (both automatic and manual), hydraulic fluids and gear fluids. The transmission, hydraulic and gear fluids containing the esters exhibit improved shear stability while maintaining desired high and low temperature viscosity characteristics.

Abstract: Nitrogen-free esters of a carboxy-containing interpolymer, wherein the interpolymer has an inherent viscosity ranging from about 0.05 to 1.5 are disclosed. The esters are useful as additives in functional fluids including transmission fluids (both automatic and manual), hydraulic fluids and gear fluids. The transmission, hydraulic and gear fluids containing the esters exhibit improved shear stability while maintaining desired high and low temperature viscosity characteristics.
