Patent

CA 2531601

Provided herein are polyurea polymers made from an organic isocyanate and a polyamine component, wherein the polyamine component comprises a polyether polyamine in which the nitrogen atoms are secondary. The polyurea polymers of the invention are useful in a wide range of end-use applications and possess superior physical properties over polyurea polymers of the prior art. Methods for producing the polyurea polymers are also disclosed.

La présente invention concerne des polymères de polyurée fabriqués à partir d'un isocyanate organique et d'un composant polyamine, le composant polyamine comprenant un polyéther polyamine dans lequel les atomes d'azote sont secondaires. Les polymères de polyurée de l'invention sont utilisés dans une large gamme d'applications d'utilisation finale et possèdent des propriétés physiques supérieures à celles des polymères de polyurée de l'état antérieur de la technique. L'invention se rapporte également à des procédés de production des polymères de polyurée précités.
