Co-condensates are prepared by condensing from 0.8 to 2.0 moles of butyraldehyde with 1 mole of a phenol at from 80.degree. to 220.degree. C. with the addition, before, during or after the condensation, of from 5 to 50% by weight, based on the mixture of phenol and butyraldehyde, of one or more thermoplastics containing functional groups, which reacts with phenol, butyraldehyde or the phenol-butyraldehyde resin under the condensation conditions. The co-condensates are used as hot-melt adhesives and as binders for nonwovens.

1,3-Diamino-2,2-dimethyl-propane is prepared by reacting hydroxypivalaldehyde with ammonia and hydrogen in the presence of a nickel catalyst at from 40.degree. to 150.degree. C. and thereafter at from 220.degree. to 300.degree. C. The product is a starting material for the manufacture of dyes, crop protection agents and plastics, especially nylons and polyurethanes.
