    Abstract: The invention relates to a method for producing shaped bodies, preferably for a film-like shaped body, comprising the following steps: I) compounding and melt extrusion of a mixture (I) comprising a mixture (II) containing a) 1 to 95 wt. % of at least a pigment (III) with a primary particle size ranging from 5 nm to 20mm, selected from the group consisting of one electrochemically inert solid (IIIa), of a compound (IIIb) capable of giving off lithium ions when charged, and a compound (IIIc), capable of receiving lithium ions when charged, and a mixture of solid (IIIa) with compounds (IIIb) or compound (IIIc), b) 5 to 99 wt. % of at least one polymer binding agent (IV), and c) 0 to 200 wt. % of at least one softening agent (V) in relation to the overall amount of constituents a) and b), wherein the weight percentage of mixture (II) in mixture (I) ranges from 1 to 100 wt. %, and excluding mixtures (I) comprising mixtures (II) containing a copolymer consisting of vinylidene fluoride (Vdf) and hexafluoropropylene (HFP) with a HFP content ranging from 8 to 25 wt. % as a polymer binding agent (IV) and a compound as a softening agent (V) which is selected from the group consisting of dibutyl phthalate, dimethyl phthalate, diethyl phthalate, tris(butoxy)ethyl phosphate, propylene carbonate, ethylene carbonate, trimethyl trimellitate and mixtures thereof.

    Abstract: The invention relates to a method for producing alkyl ketene dimers by reacting carboxylic acid chlorides with tertiary amines in a molar ratio of between 1: 1 and 1: 1.6 at temperatures of between 65 and 150 DEG C and with a residence time of between 1 and 30 mins in the absence of solvents. Said reaction partners are intensively mixed and the alkyl ketene dimers are separated from the reaction mixture.
