Title
(EN) WATER-BASED POLYURETHANE DISPERSIONS AND THEIR PREPARATION
(FR) DISPERSIONS AQUEUSES DE POLYURÉTHANE ET LEUR PRÉPARATION
Abstract
(EN)
A prepolymer comprising an acid group is made by a process comprising the step of contacting: (i) a di-isocyanate, (ii) a polyol containing an acid group, and (iii) a polyol without an acid group, the contacting conducted under reaction conditions and in a solvent consisting essentially of: (A) a first component consisting essentially of at least one glycol ether ketone, and (B) optionally, a second component consisting of at least one aprotic glycol ether. The prepolymer is useful in the preparation of water-based polyurethane dispersions.
(FR)
La présente invention concerne un prépolymère comprenant un groupe acide qui est préparé par un procédé comprenant l'étape consistant à mettre en contact : (i) un diisocyanate, (ii) un polyol contenant un groupe acide, et (iii) un polyol sans groupe acide, la mise en contact étant réalisée dans des conditions de réaction et dans un solvant constitué essentiellement de : (A) un premier composant constitué essentiellement d'au moins un éther de glycol cétonique, et (B) éventuellement, un second composant constitué d'au moins un éther de glycol aprotique. Le prépolymère est utile dans la préparation de dispersions aqueuses de polyuréthane.
