Abstract:
The invention relates to a method for producing heterogeneous water-resistant polyvinyl ester dispersions with a film formation temperature of less than 10 DEG C. According to said method, the dispersions are produced by seed polymerisation of a homopolymer or a copolymer (A) with a glass transition temperature greater than 20 DEG C, consisting of 85-100 wt. % of a vinyl ester of carboxylic acids with 1 to 18 carbon atoms, 0-10 wt. % of an alpha , beta -unsaturated carboxylic acid and/or an N-functional compound and 0-5 wt. % of an ethylenically polyunsaturated monomer, in the presence of a seed base of a copolymer B with a glass transition temperature of less than 20 DEG C, consisting of 45-98 wt. % of a vinyl ester of carboxylic acids with 1 to 18 carbon atoms, 2-50 wt. % of an alpha -olefin with 1 to 4 carbon atoms and 0-5 wt. % of an ethylenically polyunsaturated monomer. The resulting dispersions and the powders obtained therefrom by spray drying and then redispersed are suitable for use e.g., as solvent and plasticiser-free adhesives for bonding porous and semi-porous substrates.

Abstract:
The present invention provides adhesive compositions, particularly pressure sensitive adhesive compositions, comprised of from 30 weight percent to 70 weight percent of water insoluble graft copolymers dispersed in an aqueous medium. The graft copolymers are comprised of (i) from 1 weight percent to 30 weight percent of macromonomer, based on the total weight of the copolymer, wherein the macromonomer is water insoluble and has a number average molecular weight of from 2,000 to 50,000 g/mole and comprises from 85 to 100 weight percent polymerized units of at least one first ethylenically unsaturated monomer, 5 mole percent or less of polymerized mercapto-olefin compounds, and 10 weight percent or less polymerized acid-containing monomer; and (ii) from 70 weight percent to 99 weight percent of polymerized units of at least one second ethylenically unsaturated monomer, based on the total weight of the copolymer. In certain preferred embodiments, the adhesive compositions further comprise from 0.1 to 60 weight percent solids of at least one additive. The additive is selected from the group consisting of emulsifiers, defoamers, tackifiers, pigments, humectants, fillers, curing agents, thickeners, wetting agents, biocides, adhesion promoters, colorants, waxes, UV stabilizers, and antioxidants.
Abstract:
The conductive adhesive of the present invention has a multi-layer structure comprising a hydrophobic phase containing an adhesive polymer, and a hydrophilic phase containing an electrolyte. This conductive adhesive is superior in anti-drying effect (moisturizing effect) because a humectant is effectively contained in the hydrophilic phase. The present invention also relates to a biomedical electrode using such a conductive adhesive. In the biomedical electrode according to the present invention, an adhesive layer to be applied to the skin surface of the human body contains the conductive adhesive described above and an electrode terminal connected with the adhesive layer is provided.
