Size‐exclusion Chromatography of Urea‐Formaldehyde Resins
Samples of urea-formaldehyde resin have been investigated by means of size-exclusion chromatography systems: (A) Zorbax PSM packing with either pure N,N-dimethylacetamide (DMA) eluant or DMA+0.1 mol dm−3 LiNO3 eluant; (B) Styragel packing with DMA eluant. In addition to separation by size-exclusion, adsorption/partition and hydrodynamic effects were observed. The influence of reaction time and conditions on the production of large soluble aggregates was investigated briefly.
