HARDENABLE CYANATE COMPOSITIONS |
摘要 |
Disclosed are hardenable compositions based on bifunctional or polyfunctional aromatic cyanates. Said compositions comprise: a) 10 - 100 wt. %, in relation to the sum of components (a) and (b), of a bi or polyfunctional aromatic cyanate or prepolymer consisting of at least one bifunctional or polyfunctional aromatic cyanate or a mixture of the above-mentioned cyanates and/or prepolymers; b) b) 0 - 90 wt. %, in relation to the sum of components (a) and (b), of monofunctional, bifunctional or polyfunctional epoxy resin; c) 0.5 - 30 wt. %, in relation to the sum of components (a) and (b), of monofunctional or polyfunctional aromatic amine and d) 0 - 5 wt. %, in relation to the sum of components (a) and (b), of a catalyst from the group consisting of transitional metal compounds and bortirhalogenides. After hardening, the inventive compositions provide duroplastics which have a high glass transition temperature and which are especially suitable for use in the production of high-temperature-resistant moulded items for electrical appliances or the automobile and aviation construction industry. |
