Abstract
The lignophenolic resin was utilised as a component of the moulding mixtures. Its influence over the quality of the mixtures was studied. The comparison to novolac was made in order to replace the last one with lignophenolic resin. According to the obtained results, there was estimated the possibility to use the hgnophenolic resin as a great efficacious component of same sorts of moulding mixtures.
