POLYISOBUTYLENE-BASED POLYURETHANES CONTAINING ORGANICALLY MODIFIED MONTMORILLONITE |
摘要 |
The present invention generally relates to polyurethanes and polyurethane prepolymers having improved mechanical properties over ordinarily produced polyurethanes or polyurethane prepolymers. Such polyurethanes and prepolymers include very small amounts of organically-modified layered clays, and more specifically, less than 1 weight percent, based upon the total polymer composition, of a layered clay exfoliated with organic quaternary ammonium salts having alkyl substituents, wherein at least one of the alkyl substituents carries an —NH2 group. |
