Abstract
A resinous composition is composed of the ungelled reaction product of PA1 (i) a diester of oxalic acid; PA1 (ii) a material containing one or more primary and/or secondary amino groups and one or more additional functional groups; and PA1 (iii) a material capable of coreacting with (i) or (ii). The resinous composition is useful in formulating intumescent fire protective compositions for fire protection of substrates.
