ABSTRACT:
The present invention relates to quaternary .beta.-hydroxy-alkyl-ammonium halides and quaternary .beta.-hydroxy-cycloalkylammonium halides, which are liquid at temperatures lower than 60.degree. C., are easily and rapidly miscible in liquid epoxides, as well as in liquid poly-isocianates, generating liquid compositions which spontaneously polymerize, with fast polymerization rate, already at temperatures comprised within the range of from 0.degree. C. to 60.degree. C., yielding a solid, insoluble polymeric material endowed with very high values of softening temperature.
