Title (EN) PREPARATION OF MICROCELLULAR POLYURETHANE ELASTOMERS
(FR) PREPARATION D'ELASTOMERES DE POLYURETHANE MICROCELLULAIRES
Abstract:
(EN) Improved integral skin microcellular polyether polyurethane elastomer products, e.g., shoe soles, which are characterized by outstanding low temperature dynamic flex and green strength at demold, at specific gravities as low as about 0.4 gm/cc. These elastomer products are desirably prepared from a two-component system, e.g., the reaction of Package A containing improved normally liquid quasi-prepolymers, with Package B comprising a compatible liquid mixture containing polymer/poly(oxyethyleneoxypropylene)polyol, difunctional chain extender, halogenated blowing agent and optionally other ingredients. The said liquid quasi-prepolymers are derived from the reaction of (1) a mixture of normally solid diphenylmethane diisocyanate, carbodiimide and/or uretone imine and (2) poly(oxyethyleneoxypropylene)polyols.
(FR) Produits améliorés d'élastomères de polyuréthane de polyéther microcellulaires à enveloppe intégrale, par exemple des semelles de chaussures caractérisées par une excellente flexion dynamique à basse température et une cohésion à vert lors du démoulage, à des poids spécifiques aussi bas que 0,4 gm/cc. Ces produits élastomères sont préparés avantageusement à partir d'un système à deux composants, par exemple la réaction d'un paquet A contenant des quasi-prépolymères améliorés normalement liquides avec un paquet B comportant un mélange liquide compatible contenant un polymère/poly(oxyéthylèneoxypropylène)polyol, un allongeur de chaîne bifonctionnel, un agent gonflant halogéné et facultativement d'autres ingrédients. Lesdits quasi-prépolymères liquides sont dérivés de la réaction (1) d'un mélange de diisocyanate de diphénylméthane normalement solide, de carbodiimide et/ou d'urétone-imine et (2) de poly(oxyéthylèneoxypropylène)polyols.
