  • Publication number: 20110089075
    Abstract: A method of coating containers made of glass, polyethylene or polyester by treatment with a substantially paraffin-free aqueous formulation comprising (A) at least one acid-functional waxy copolymer selected from (A1) partially oxidized polyethylene waxes having an acid number in the range from 10 to 100 mg KOH/g, determined in accordance with DIN 53402, with (A2) copolymers having a melt flow rate (MFR) in the range from 1 to 50 g/10 min, measured at 160° C. under a load of 325 g in accordance with EN ISO 1133, which in copolymerized form comprise (a) 60% to 88% by weight of ethylene, (b) 12% to 40% by weight of at least one ethylenically unsaturated carboxylic acid, and which are at least partially neutralized with alkali metal or amine, (B) if desired, at least one nonionic or anionic surfactant, (C) if desired, at least one defoamer, (D) if desired, at least one organic amine, (E) if desired, at least one organic solvent.

  • Publication number: 20100266792
    Abstract: Composite materials comprising at least one natural fiber, at least one thermoplastic polymer, and at least one random copolymer having a molar mass Mn of up to 20,000 g/mol. The random copolymer is produced from the copolymerization of ethylene and at least one comonomer. The comonomer is selected from the group consisting of ethylenically unsaturated C3-C10 monocarboxylic acids; ethylenically unsaturated C4-C10 dicarboxylic acids or their anhydrides; epoxy esters of ethylenically unsaturated C3-C10 monocarboxylic acids, and (b4) comonomers of the general formula I: wherein R1 and R2 are a hydrogen or an unbranched or branched C1-C10-alkyl; R3 is identical or different and is a hydrogen, unbranched and branched C1-C10-alkyl or C3-C12-cycloalkyl, where two radicals R3 may be bonded together to form a 3-10-membered ring; X is an oxygen, sulfur or N—R4; R4 is an unbranched or branched C1-C10-alkyl; and A1 is a divalent group selected from C1-C10-alkylene, C4-C10-cycyloalkylene, and phenylene.
