    Abstract: Moulding materials based on polyethylene having a density of 0.915 to 0.940 g./cm.3 contain as an antistatic agent 0.01 to 5% by weight of an amide of the formula R-CONR1R2 in which R denotes an aliphatic hydrocarbon radical having 7-29 carbon atoms, R1 denotes H or R2, and R2 denotes the group -(A-O)m-(B-O)n-(D-O)pH, in which A, B and D are the same or different alkylene radicals of 2-4 carbon atoms, and the total of m+n+p is an integer of from 8-22 when R1 is H and an integer of from 4-11 when R1=R2. Additives such as fillers, dyes, light stabilizers, heat stabilizers, lubricants and anti-blocking agents (all unspecified) may also be included. Products such as film, sheeting, sections and household articles may be obtained from the moulding material which is generally in granular form.

    Abstract: A stoving lacquer contains (I) water, and (II) a mixture of (1) 65 to 75% by weight of at least one water-soluble salt of (a) at least one water-soluble volatile tertiary amine and (b) a copolymer comprising 82 to 88% isobutyl acrylate, 8 to 12% acrylic acid and 4 to 6% of N-(hydroxymethyl) methacrylamide, the sum of the percentages of these monomers being 100%, and (2) 35 to 25% of a water-soluble cocondensate of formaldehyde, a 1:3 to 1:6 by weight mixture of 2,2-bis-(p-hydroxyphenyl)-propane and phenol and, optionally, at least one alkanol having 1 to 4 carbon atoms. Suitable amines (a) are trimethylamine, tri-(b -hydroxyethyl) - amine, N,N - dimethyl - N - (b - hydroxypropyl) - amine, triethylamine and N,N - dimethyl - N - (b - hydroxyethyl) - amine. The lacquers may also contain organic solvents, e.g. monoalkyl ethers of diethylene and triethylene glycol, hexavalent chromium compounds, e.g. ammonium dichromate and pigments, e.g. TiO2. In examples, the lacquers are applied to sheet metal, exposed to air and stoved (see Division B2).ALSO:A stoving lacquer comprises (I) water and (II) a mixture of (1) 65 to 75% of at least one water soluble salt of (a) at least one water-soluble volatile tertiary amine and (b) a copolymer containing 82 to 88% isobutyl acrylate, 8 to 12% acrylic acid and 4 to 6% of N-(hydroxymethyl) methacrylamide and (2) 35 to 25% of a water soluble cocondensate of formaldehyde and a 1:3 to 1:6 mixture of 2, 2 bis - (p - hydroxyphenyl) - propane and phenol.
