    摘要: Thermosettable prepolymers or resins are prepared by reacting (1) a pyrazine compound containing at least two substituent groups which have a hydrogen atom attached to a carbon atom which is attached to the ring such as tetramethylpyrazine, (2) a material containing at least two aromatic aldehyde groups, and (3) at least one of (a) a nitrogen containing aromatic heterocyclic compound containing at least one hydrogen atom attached to a carbon atom attached to the ring and a polymerizable unsaturated group such as 2-methyl-5-vinylpyridine or (b) an aldehyde containing at least one polymerizable unsaturated group such as 4-isopropenyl-1-cyclohexane-1-carboxaldehyde. These prepolymers or resins are curable to thermoset products having good mechanical and thermal properties by heat and pressure or by homopolymerization or copolymerization with N,N'-bis-imides such as 1,1'-(methylenedi-4,1-phenylene)bismaleimide. The prepolymers are suitable for preparing composites.

    摘要: Thermosettable compositions are disclosed which are prepared by reacting (A) a pyridine compound containing at least two substituent groups which have at least one hydrogen atom attached to a carbon atom which is attached to the ring or mixture of such pyridines; (B) at least one material having at least two aldehyde groups; and (C) at least one aldehyde containing at least one polymerizable unsaturated group; wherein components (A), (B) and (C) are employed in quantities which provide a mole ratio of (C):(B):(A) of from about 0.25:0.25:1 to about 4:4:1. These thermosettable compositions can be cured by heat and pressure or by homopolymerization in the presence of or by copolymerization with an N,N'-bis-imide. The compositions are useful as light weight fire resistant interior and exterior parts or panels for the aerospace and/or aircraft industry and the like.
