    Abstract: PROBLEM TO BE SOLVED: To provide a pressure sensitive adhesive having an improved adhesive power and/or cohesive power. SOLUTION: This adhesive consists of a polymer including 60 to 95 wt.% of a monomer mixture (monomer a) comprising one or more kinds of 4C alkylacrylate and one or more kinds of 6 to 12C alkylacrylate, 5 to 30 wt.% of ethylenic unsaturated compound(monomer b) excluding other functional groups except ethylenic unsaturated group and the polymer of this monomer has glass transition temperature >=0 deg.C, 0 to 10 wt.% of an ethylenic unsaturated compound (monomer c) including one or more acid group or acid anhydride group, and 0 to 20 wt.% of other ethylenic unsaturated compound (monomer d), the weight ratio in wt.% is based on the obtained polymer, and the polymer dispersion includes an emulsifier including at least 5 wt.% of aromatic carbon atoms (abbreviated as aromatic emulsifier) or an emulsifier mixture comprising at least 10 wt.% of the aromatic emulsifier.

    Abstract: Contact adhesive dispersions contain (A) an aqueous dispersion of a copolymer A which has a glass transition temperature below 0 DEG C. and consists of (a) from 50 to 99% by weight of esters of acrylic acid with non-tertiary alkanols, (b) from 0 to 50% by weight of esters of acrylic or methacrylic acid and/or vinyl esters and/or (meth)acrylonitrile and/or styrene and/or tert.-butyl acrylate, (c) from 0.5 to 5% by weight of monoolefinically unsaturated carboxylic acids and/or their amides which are unsubstituted or substituted at the nitrogen atoms by alkyl and/or alkylol radicals, and/or hydroxyalkyl (meth)acrylates, and (d) from 0.5 to 5% by weight of carbonyl-containing monomers and (B) from 0.05 to 2 moles of a water-soluble dihydrazine compound per mole of carbonyl groups present in the copolymer A.

    Abstract: The invention relates to a process for reducing the permeation of blow-moulded hollow bodies made of thermoplastics, in particular of high molecular weight HDPE, in which the hollow body surfaces are flame-treated by means of a gas flame or are subjected to the effect of an electrical discharge in a gaseous atmosphere and subsequently, in a special operation, coated with a coating composition which is permeable only to a slight extent, if at all, to the filling material and/or the medium surrounding the hollow body. The coating material used are moisture-curing polyurethane prepolymers containing approximately 10 to approximately 90% by weight of fillers, homogeneously distributed. The fillers can also be applied in the form of an additional layer subsequently during the curing phase of the polyurethane prepolymers. The hollow bodies thus treated are suitable for storing hydrocarbon mixtures.
