Moisture and gas permeable non-porous ionomeric films

Moisture and gas permeable ionomeric films are described. The films described herein are obtained from blends of ionomers with an organic acid salt in the amount of at least about 5 wt %, and have MVTR greater than films obtained from conventional ionomers. Particularly preferred are the potassium salts of stearic, oleic, isostearic, and isooleic acids. Films comprising a liquid-absorbent ionomer film layer and an impermeable layer are provided. The films are suitable for preparation of tubular casings and shrinkbags, in particular, casings for smoked foodstuffs.

Preparation method of anti-cracking zinc acrylate antifouling paint

The invention discloses a preparation method of an anti-cracking zinc acrylate antifouling paint. The preparation method comprises synthesis of a zinc acrylate small-molecular monomer, synthesis of a zinc acrylate polymer and preparation of zinc acrylate antifouling paint, wherein the zinc acrylate small-molecular monomer contains a first solvent, zinc oxide, a methacrylic acid monomer and monocarboxylic acid; the zinc acrylate polymer contains a second solvent, a zinc acrylate small-molecular monomer, a methacrylate monomer and an initiator; the zinc acrylate antifouling paint contains a zinc acrylate polymer solution, pigment filler, a third solvent, an antifouling agent and an auxiliary; the structural formula of the synthesized zinc acrylate polymer is shown in the specification; the long branch of isostearic acid in monocarboxylic acid has relatively good internal plasticization function so that the synthesized zinc acrylate polymer has relatively good flexibility; and the methacrylate monomer is of a aliphatic six-membered ring structure with a cyclohexyl structure, the damage of the antifouling paint caused by excessive internal stress can be avoided, and the anti-cracking performance of the antifouling paint is enhanced.

Method for separating and extracting isostearic acid from monomer acid

The present invention discloses a method for separating and extracting isostearic acid from monomer acid. The present invention relates to a method for separating and extracting isostearic acid, in particular to a novel method for separating and extracting isostearic acid from monomer acid. The present invention provides a method for separating and extracting isostearic acid from monomer acid, which is suitable for use in commercial production. The method is characterized in: esterify the byproduct (monomer acid) obtain in production of dimer acid through bleaching earth catalytication process under medium pressure without catalyst to obtain monomer acid ester, treat by catalytic hydrogenation under medium pressure, and filter to obtain hydrogenised monomer acid ester; envelope with carbamide, filter, separate, and wash with water to obtain crude product of isostearic acid ester; perform molecular distillation to obtain refined isostearic acid ester, and then perform hydrolysis to obtain isostearic acid. Compared to the separation and extraction technique in the prior art, the present invention has the following advantages: the acidity and viscosity are low during hydrogenisation, and therefore the service life of catalyst is long, no nickel soap will be formed, and the corrosion to equipment is reduced; the product can be enveloped and separated by carbamide more easily; the distillation can be performed at a lower temperature; the iodine value of final product is low, the color is light, and the purity is high.
