Beschreibung
Zusammenfassung:	A bulk moulding compound comprising one or more cyanate ester, a catalyst, a filler and reinforcement fibres is provided, whereby the one or more cyanate ester is independently selected from a difunctional cyanate ester compound and/or a polyfunctional cyanate ester and mixtures of these cyanate esters. Furthermore, the catalyst is independently selected from the group consisting of 4,4' methylene- bis(2,6-diethylaniline) (M-DEA), 4,4'-methylene-bis(3-chloro-2,6- diethyl-aniline) (M-CDEA), aluminum(lll)acetylacetonate, and mixtures thereof. L'invention concerne un composé de moulage en vrac comprenant un ou plusieurs ester de cyanate, un catalyseur, une charge et des fibres de renforcement, le ou les esters de cyanate étant indépendamment choisis parmi un composé d'ester de cyanate bifonctionnel et/ou un ester de cyanate polyfonctionnel et des mélanges de ces esters de cyanate. En outre, le catalyseur est choisi indépendamment dans le groupe constitué par la 4,4'méthylène-bis(2,6-diéthylaniline) (M-DEA), la 4,4'-méthylène-bis(3-chloro -2,6-diéthyl-aniline) (M-CDEA), l'acétylacétonate d'aluminium (lll) et leurs mélanges.
