description | The present disclosure relates to polyurethanes comprising a reaction product of a reactive mixture including a polyol having a number average molecular weight of at least 400 Daltons, a diol chain extender having a molecular weight less than 400 Daltons, a diisocyanate; and a multifunctional amine. The present disclosure further provides polishing layers and polishing pads fabricated therefrom. Additionally, the present disclosure provides polishing systems and polishing methods employing said polishing layers and polishing pads.
La présente divulgation concerne des polyuréthanes comprenant un produit de la réaction d'un mélange réactif contenant un polyol ayant une masse moléculaire moyenne en nombre d'au moins 400 Daltons, un extendeur de chaîne de type diol ayant une masse moléculaire inférieure à 400 Daltons, un diisocyanate ; et une amine multifonctionnelle. La présente divulgation porte en outre sur des couches de polissage et sur des tampons de polissage fabriqués à partir de ceux-ci. En outre, la présente divulgation concerne des systèmes de polissage et des procédés de polissage utilisant lesdits tampons de polissage et couches de polissage. |
