A method for producing a silylated polyurethane that comprises the following steps: (1) reacting at least one polyether polyol having a number average molecular weight of at least 2,000 g/mol with at least one polyisocyanate in the presence of at least one solvent; (2) reacting the reaction product of step (1) with at least one silane of formula (I) A-R&#x2014;SiXYZ (I), where A means &#x2014;NHor &#x2014;NHB, wherein B stands for a branched or linear alkyl radical with 1-12 C atoms, possibly having functional groups, a cyclic alkyl radical having 5-8 C atoms, or an aryl radical, R is a divalent hydrocarbon radical having 1-12 C atoms, and X, Y, Z are substituents on the Si atom and are independently of each other C-Calkyl, C-Calkoxy or C-Cacyloxy groups, wherein at least one of radicals X, Y, Z is a C-Calkoxy or C-Cacyloxy group, in the presence of at least one solvent. Further disclosed is a silylated polyurethane that can be produced by the method, a curable composition based thereon, and the use of such a composition as an adhesive, sealant and/or coating material.

A solvent-free and anhydrous hardenable composition that contains at least one polymer A. Polymer A being obtainable by reacting a polyether with at least one ethylenically unsaturated silane in the presence of a radical starter, the ethylenically unsaturated silane carrying at least one hydrolyzable group on the silicon atom. The composition provides low viscosity prior to curing along with good elasticity after curing and a broad adhesion spectrum in a solvent-free and water-free hardenable composition. Also methods for producing the composition and use of the composition as an adhesive, sealant, or coating agent.

Methods of preparing polyolefin-based molded materials with improved adhesive/coating compatibility by incorporating saturated fatty acid amides and transition metal compounds in the polyolefin-based material prior to molding are described. Methods of producing coated or bonded polyolefin-based, molded materials are also described.

Methods of preparing polyolefin-based materials having improved adhesive/coating compatibility

Methods of preparing polyolefin-based molded materials with improved adhesive/coating compatibility by incorporating aromatic carboxylic acid amides and transition metal compounds in the polyolefin-based material prior to molding are described. Methods of producing coated or bonded polyolefin-based, molded materials are also described.

A process for making a polyolefin composition having improved adhesive and/or coating compatibility involving: (a) providing a polyolefin; (b) providing from 0.01 to 10% by weight, based on the weight of the polyolefin, of a migratable amphiphile; (c) providing from 0.01 to 1000 ppm, based on the weight of the polyolefin, of a transition metal selected from the group consisting of titanium, tin, and mixtures thereof; and (d) combining (a)-(c) to form the polyolefin composition.

An aqueous hair-treatment preparation containing an antistatic additive imparting an antistatic effect to the hair, characterized in that said antistatic additive is at least one cationic polymer produced by the process of (1) epoxidizing 1,3-diene homopolymers or copolymers, (2) amine reacting the epoxide compound so produced with low molecular weight amines selected from the group consisting of primary amines, secondary amines and tertiary amines, and (3) converting the reaction products into the salt form or into polymeric quaternary ammonium salts. The use of these polymeric amine salts or quaternary ammonium salts in cosmetic hair-treatment preparations provides these preparations with antistatic effects. Preferred cationic polymers are obtained by the expoxidation of polybutadiene, of which more than 50% of the monomer units show the 1,4-cis- configuration, reaction with dimethylamine or morpholine and conversion into the hydrochlorides or alkylation with glycidyl trimethylammonium chloride, 3-chloro-2-hydroxypropyl trimethylammonium chloride or ethylene oxide. The cationic polymers are preferably used in shampoos in quantities of from 0.5 to 5.0% by weight in addition to 5 to 30% by weight of alkylether sulfate tensides and 1 to 5% by weight of a zwitterionic or amphoteric washing-active substance.
