Abstract
The invention provides application of an active-hydrogen-containing heterocyclic compound to preparation of phthalonitrile resin. The active-hydrogen-containing heterocyclic compound is one of active-hydrogen-containing carbazole, active-hydrogen-containing imidazole, active-hydrogen-containing pyrimidine, active-hydrogen-containing purine, active-hydrogen-containing piperazine, active-hydrogen-containing pyrrole, active-hydrogen-containing pyrazole, active-hydrogen-containing indazole, active-hydrogen-containing indole, active-hydrogen-containing pyrrolo-pyridine and active-hydrogen-containing phthalazinone. According to the new application of the active-hydrogen-containing heterocyclic compound, namely application of the active-hydrogen-containing heterocyclic compound to preparation of phthalonitrile resin, provided by the invention, the active-hydrogen-containing heterocyclic compound is used as a curing agent to accelerate curing of phthalonitrile resin, and meanwhile, heat stability and heat oxygen stability of phthalonitrile resin are improved.
Description
Technical field
The invention belongs to processing of high molecular material technical field, more particularly to heterocyclic compound containing reactive hydrogen are preparing adjacent benzene
Application in dimethoxy nitrile resin.
Background technology
Heterocyclic compound (heterocyclic compound) refers to the class compound with circulus.Constitute ring
Atom carbon atom outside, also at least contain a hetero atom (non-carbon), hetero atom includes oxygen, sulfur, nitrogen etc..Heterocyclic compound
