Hybrid Polymers from Cyanates and Silazanes, Process for Their Production and Use |
摘要 |
This invention refers to hybrid pre-polymers and polymers, produced through conversion from difunctional, oligofunctional and/or polyfunctional cyanates and/or from their pre-polymers with monomeric, oligomeric and/or polymeric silazanes. The polymers are duromers with high glass transition temperature and fracture toughness, compared to duromers from the respective cyanate source material. In their pre-polymerized state, they can be dissolved in solvents and are therefore suitable as impregnating resins for prepregs. In addition, they can be processed to become moldings. Their burning properties are described as particularly outstanding. |
