COMPOSITION FOR IMPROVING LOW-TEMPERATURE PROPERTIES AND RESISTANCE TO OXIDATION OF VEGETABLE OILS AND ANIMAL FAT

摘要

1. A composition containing (A) from 35 to 50 wt. % of at least one polyalkyl (meth) acrylate polymer; (B) from 5 to 15 wt. % of at least one ethylene-vinyl acetate copolymer, including fragments derived from at least one alkyl (meth) acrylate containing 1-30 carbon atoms in the alkyl residue; (C) from 10 to 20 wt. % phenolic type antioxidant; (D) 10 to 25 wt. % stabilizer mixture; and (E) from 10 to 20 wt. % glycol ether solvent where the sum of all components (A) - (E) in the composition is 100 wt. % .2. The composition of claim 1, wherein said at least one polyalkyl (meth) acrylate polymer in component (A) contains: (a) from 0 to 40 wt. %, based on the total weight of the polymer, of fragments derived from one or more alkyl (meth) acrylate monomers of the formula (I) where R is a hydrogen atom or methyl, and R is a linear, branched or cyclic alkyl residue containing 1-6 carbon atoms, in particular 1-5, and preferably 1-3 carbon atoms; (b) from 40 to 99 wt. %, based on the total weight of the polymer, of fragments derived from one or more alkyl (meth) acrylate monomers of the formula (II) where R is a hydrogen atom or methyl, and R is a linear, branched or cyclic alkyl residue containing 7-15 carbon atoms; and (c) from 0.1 to 40 wt. %, based on the total weight of the polymer, of fragments derived from one or more alkyl (meth) acrylate monomers of the formula (III) where R is a hydrogen atom or methyl, and R is a linear, branched or cyclic alkyl residue containing 16-30 carbon atoms, where the sum of all components (a) - (c) is 100 wt. % .3. The composition of claim 1, wherein the ethylene-vinyl acetate copolymer in component (B) contains: (i) from 2 to 40 wt. % vinyl acetate; (ii) from 30 to 80 wt. %
