摘要:
Moldings, in particular foams and fibers, based on melamine/formaldehyde condensation products, in which from 0.1 to 70 mol % of the melamine have been replaced by melamine substituted by from 1 to 3 hydroxyoxaalkyl groups of the formula--(CH.sub.2 --CH.sub.2 --O).sub.n --CH.sub.2 --CH.sub.2 --OHn=1-5)have increased elasticity.
