Abstract
Questa invenzione si riferisce ad una composizione di poliisocianato uretano-modificato e al suo uso nella preparazione di elastomeri di poliuretani microcellulari, preferibilmente elastomeri espansi con acqua ottenuti da un polietere poliolo. Il poliisocianato uretano-modificato è ottenuto facendo reagire, in presenza di un polimero in particelle, un poliisocianato comprendente almeno 50% in peso di 4,4' - MDI con una composizione isocianato-reattiva contenente: i) un diolo o triolo ramificato avente un peso molecolare da 60 a 400 e ii) un polietere poliolo con una funzionalità da 2 a 4, un peso molecolare da 1000 a 12000. I componenti i) e ii) sono presenti secondo un rapporto in peso da 0,01 a 0,25:1. Il polimero organico in particelle è presente in una quantità tale che il contenuto di sostanze solide della composizione di poliisocianato uretano-modificata è da 1 a 10% in peso.
