Title
(EN) ELASTOMERIC POLYURETHANES WITH IMPROVED PROPERTIES BASED ON CRYSTALLIZABLE POLYOLS IN COMBINATION WITH LOW MONOL POLYOXYPROPYLENE POLYOLS
(FR) POLYURETHANNES ELASTOMERES A CARACTERISTIQUES AMELIOREES, A BASE DE POLYOLS CRISTALLISABLES COMBINES A DES POLYOLS POLYOXPROPYLENE A FAIBLE TENEUR EN MONOL
Abstract
(EN)
Polyurethane elastomers of improved elongation, tensile strength and other physical properties are prepared from a polyol component containing a cristallizable polyol and from 5 to 35 equivalent percent of a low monol polyoxypropylene polyol by one-shot, quasi-prepolymer, and preferably, by prepolymer techniques involving chain extension with an aliphatic diol or aromatic amine.
(FR)
On prépare des polyuréthannes élastomères à caractéristiques d'allongement, de résistance à la traction et autres caractéristiques physiques améliorées à partir d'un constituant polyol contenant un polyol cristallisable et de 5 à 35 équivalents par cent d'un polyol polyoxypropylène à faible teneur en monol au moyen de techniques impliquant des quasi-prépolymères et de préférence des prépolymères, selon un procédé en une seule phase, comprenant l'extension de chaîne avec un diol aliphatique ou une amine aromatique.
