ABSTRACT 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 thermo- settable 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 composi- tions are useful as light weight fire resistant interior and exterior parts or panels for the aerospace and/or aircraft industry and the like.
