Intumescent laminate with high heat transfer resistance composed of a glass-fiber web or glass-fiber fabric each of which has been coated with a four-component intumescent composition comprising a) a phosphate compound, b) a melamine compound, c) a polyol and d) an inorganic framework-forming compound.

Intumescent laminates with high heat transfer resistance

A diamine or bismaleimide of the general formula I ##STR1## in which R.sub.1 and R.sub.2 denote an H atom or together denote the group --OC--CH.dbd.CH--CO--, Y.sub.1 and Y.sub.2 independently of one another denote O or S and Het denotes a thiazole, a thiadiazole or a 1-methyltriazole ring. The diamines and bismaleimides are used for the preparation of polyimides which are if appropriate reinforced with fibers and if appropriate incompletely hardened.

Polyimide from diamine and bismaleimide having azole ring

A thermally expandable fire-protection compound consisting of expandable graphite, an aqueous chloroprene latex containing carboxyl groups, and substances which, in the event of fire, form a paracrystalline carbon skeleton.

Thermally expandable fire-protection composition comprising expandable

Bismaleimides of the formula I ##STR1## wherein R denotes a radical of the formula II ##STR2## and polyimides which can be prepared from these bismaleimides, if appropriate with the addition of an aromatic diamine. The polyimides are optionally reinforced with fibers.
