Abstract
A study has been made of the influence of introducing a linear macromolecular matrix (polyacrylic acid) on the polycondensation of urea and formaldehyde in aqueous media, and on the properties of the resulting products. It is shown that the character of the products changes gradually as the polyacid concentration is increased. The structure, swelling in aqueous media, mechanical properties and thermal degradation of the polycomplexes containing urea-formaldehyde resin and polyacrylic acid have been investigated. It is shown that all the properties of the polycomplexes differ significantly from those of the individual components. The results show that polycomplexes based on the products of three-dimensional polycondensation are obtainable when the process is carried out in the presence of linear macromolecular matrices.
