Abstract

Elastomères de polyuréthane. Ces élastomères comprennent un produit réactionnel de A. un diol polymère ayant un poids moléculaire d'environ 800-5 000; B. un mélange de diisocyanates organiques où environ 2-70 % en mole sont composés de diisocyanate aliphatique (ce diisocyanate n'ayant pas de liaison directe entre un noyau aromatique et un groupe isocyanate) et où le complément (98-30 % en mole) est composé de diisocyanate aromatique qui comprend une liaison directe entre un noyau aromatique et un groupe isocyanate; et C. un produit d'extension de chaîne comprenant de l'hydraxine et/ou un dérivé de ce produit, ayant la formule NH2 NHR où R est notamment l'hydrogène, un groupe alkyle ou un groupe aryle, et un autre produit d'extension de chaîne ayant deux groupes fonctionnels constituant des groupes amino et/ou hydroxyles où environ 30-80 % des atomes de carbone qui sont liés aux atomes d'azote constituant les liaisons urélylènes et/ou uréthanes de cet élastomère de polyuréthane constituent des squelettes à noyaux benzéniques et/ou naphtaléniques et/ou environ 2-70 % des liaisons uréylènes de l'élastomère de polyuréthane sont formés par la réaction de diisocyanate aliphatique et d'hydrazine et/ou de ses dérivés ayant la formule NH2 NHR, où R est tel que défini précédemment. La présente invention est particulièrement utile pour fournir des matières en feuilles composites, présentant une longévité améliorée lors d'une exposition aux agents atmosphériques, ainsi qu'une excellente résistance à l'abrasion.
