The current invention concerns a textile coating composition comprising an aqueous emulsion of a midblock sulfonated styrenic block copolymer and a poly(vinyl alcohol). It also concerns a method for preparing the textile coating composition and its application. It also concerns fabrics on which the coating compositions have been applied.

Textile coating composition

Accordingly, the invention provides a process for the preparation of an artificial latex, comprising the steps: (a) emulsification of a cement comprising a rubber dissolved in a suitable organic solvent, together with an aqueous surfactant solution, thus forming an oil-in-water emulsion; (b) step-wise reduction of the solvent content of the oil-in-water emulsion in two or more stages resulting in an artificial latex. In addition, the invention provides a continuous stirred vessel for removing an organic solvent from an oil-in-water emulsion comprising rubber dissolved in an organic solvent.

Process for the preparation of an artificial latex

A process of producing an artificial latex, comprising the steps:

Purifying reagent for the purification of starting materials to be used in a metal compound catalyzed polymerization, containing proton donating reactive contaminants, consisting of a solid product, obtainable by the metallation of a product of a nucleophilic displacement reaction between a halogen alkylated crosslinked poly(vinylaromatic) resin and a metallated conjugated diene compound, which product is insoluble inorganic solvents, which is not able to initiate anionic polymerization of olefins or dienes and which is able to scavenge proton donating contaminants, which may hamper polymerizations catalysted by metal organic compounds; and process for purification of starting materials applying said purifying reagent.

Process for purification of starting materials for metal catalyzed

Purifying reagent for the purification of starting materials to be used in a metal compound catalyzed polymerization, containing proton donating reactive contaminants, consisting of a solid product, obtainable by the metallation of a product of a nucleophilic displacement reaction between a halogen alkylated crosslinked poly(vinlyaromatic) resin and a metallated conjugated diene compound, which product is insoluble inorganic solvents, which is not able to initiate anionic polymerization of olefins or dienes and which is able to scavenge proton donating contaminants, which may hamper polymerizations catalysted by metal organic compounds; and process for purification of starting materials applying said purifying reagent.
