Title (EN) A POLYISO-UREA
(FR) POLYISO-URÉE
Abstract: front page image
(EN)A composition for forming a polyiso-urea includes a capped polycarbodiimide and a polyol. The capped polycarbodiimide comprises the reaction product of a diisocyanate and a monoisocyanate in the presence of an oxygen scavenger and a carbodiimidization catalyst and in the absence of solvent, has 0.25 wt. % or less of free isocyanate groups, and is a liquid at 25°C. A polyiso-urea comprises the reaction product of the capped polycarbodiimide and the polyol.
(FR)Une composition permettant la formation d'une polyiso-urée comprend un polycarbodiimide coiffé et un polyol. Le polycarbodiimide coiffé comprend le produit réactionnel d'un diisocyanate et d'un monoisocyanate en présence d'un désoxygénant et d'un catalyseur de carbodiimidisation et en l'absence de solvant, comporte au maximum 0,25 % en poids de groupes isocyanate libres, et se présente sous la forme d'un liquide à 25 °C. Une polyiso-urée comprend le produit réactionnel du polycarbodiimide coiffé et du polyol.
