Title (EN) POLYISOCYANATE COMPOSITIONS CONTAINING RIGID COMPOUNDS OR POLYMERS, AND POLYURETHANES PREPARED THEREFROM
(FR) COMPOSITIONS DE POLYISOCYANATES CONTENANT DES COMPOSES RIGIDES OU DES POLYMERES, ET POLYURETHANES PREPARES A PARTIR DE CES COMPOSITIONS
Abstract:
(EN) This invention relates to polyisocyanates containing dissolved or colloidally dispersed polymers containing rigid moieties. Included among the dissolved or colloidally dispersed polymers are polymers of ethylenically unsaturated polyaromatic compounds, ethylenically unsaturated benzoic acid derivatives, ethylenically unsaturated steroid derivatives, and rigid aromatic polyurethane and/or polyurea polymers. The dissolved or colloidally dispersed polymers provide substantial reinforcemement and physical property improvememnt to polyurethane or polyurea polymers made from the polyisocyanate solution or dispersion.
(FR) Cette invention concerne des polyisocyanates contenant des polymères dissous ou dispersés dans un colloïde, lesquels polymères contiennent des fractions rigides. Les polymères dissous ou dispersés dans un colloïde peuvent être des polymères de composés polyaromatiques à insaturation éthylénique, des dérivés de l'acide benzoïque à insaturation éthylénique, des dérivés de stéroïde à insaturation éthylénique, et des polymères de polyurée et/ou polyuréthane aromatiques rigides. Les polymères dissous ou dispersés dans un colloïde constituent un renforcement sensible et une amélioration des propriétés physiques des polymères de polyurée ou de polyuréthane obtenus à partir de la dispersion ou solution de polyisocyanate.
