AMPHYTIFUL GRAFT BASED POLYMERS BASED ON GRAIN BASES CONTAINING AMIDA UNITS OF THE N-VINYL CARBOXYL ACID, A PROCEDURE FOR OBTAINING AND EMPLOYMENT.

摘要

THE INVENTION REFERS TO AMPHIFILIC GRAFT POLYMERS, IN WHICH THE BASE OF THE GRAFT IS A POLYMER THAT CONTAINS AT LEAST 5% BY WEIGHT OF FORMULA UNITS (I) AND, OPTIONALLY, FORMULA UNITS (II), BEING R 1 , R 2 HO RENT-C 1 -C 6, CHARACTERIZED BECAUSE (A) THE STYRENE, THE RENTED C 1 -C 2 AND / OR THE VINYLTOLUENE, AND OPTIONALLY (B) OTHER MONO-ETHENICALLY INSATURED MONOMEROS THAT CAN BE COPOLIMERIZED, ON THE BASE OF GRAFT IN A RELATIONSHIP IN WEIGHT OF 1:99 AND 99: 1, AND BECAUSE GROUP (C) IS SCALED PARTIALLY OR FULLY OF THE GRAY POLYMERS, FORMING AMINO GROUPS. THE INVENTION IS EQUALLY CONCERNING PROCEDURES FOR THE PREPARATION AND USE OF AMPHYPHYLENE GRAFT POLYMERS AS PAPER CONSOLIDATION AGENTS, AS AGENTS FOR FIXING, SOLUBLE AND INSOLUBLE AGENTS IN WATER, WHICH PRODUCE ALTERATIONS IN THE MANUFACTURE OF PAP OF INORGANIC AND ORGANIC PIGMENTS, COLORS, AGENTS OF PROTECTION OF THE CONCRETE AND OF THE PLANTS, ADDITIVES FOR DETERGENTS, MATERIAL OF COATINGS AND PHYTO-PROTECTING AGENTS, AS AGENTS FOR THE MAINTENANCE OF THE SOILS, AS COLOSERS FOR COSMETIC FORMULATIONS, AS AGENT CONDITIONERS FOR SKIN CARE AND AS A COMPONENT OF COSMETIC PREPARATIONS FOR HAIR AND COSMETIC PREPARATIONS FOR ORAL HYGIENE.
