Abstract

Abstract Translated from German Die Erfindung betrifft Additive für Mineralöle auf Basis von Polyalkylmethacrylaten mit stockpunktverbessernder Wirkung, wobei die Additive aus einem Polymerisat P aufgebaut aus a) 10 -30 Mol-% Methylmethacrylat b) 10 -70 Mol-% Alkylmethacrylaten mit unverzweigten Alkylresten mit 16 -30 Kohlenstoffatomen im Alkylrest, c) 80 -0 Mol-% Alkylmethacrylaten mit unverzweigten Alkylresten mit 4 -15 Kohlenstoffatomen und/oder verzweigten Alkylresten mit 4 -40 Kohlenstoffatomen im Alkylrest und gegebenenfalls d) 30 -0 Mol-% eines dispergierwirksamen, stickstoffhaltigen radikalisch polymerisierbaren Monomeren als Monomerkomponenten bestehen. The invention relates to additives for mineral oils based on polyalkyl methacrylates with a pour point-improving effect, the additives being composed of a polymer P. a) 10 -30 mol% methyl methacrylate b) 10 -70 mol% of alkyl methacrylates with unbranched alkyl radicals with 16-30 carbon atoms in the alkyl radical, c) 80-0 mol% of alkyl methacrylates with unbranched alkyl radicals with 4 -15 carbon atoms and / or branched alkyl radicals with 4 -40 carbon atoms in the alkyl radical and optionally d) 30-0 mol% of a dispersing, nitrogen-containing, free-radically polymerizable monomer exist as monomer components.
