Abstract

Flexible abrasive articles are prepared containing a condensation product of an aldehyde and a urea such as urea, thiourea, mono- or dimethylolurea, diphenyl-urea or -thiourea or di-p-tolylurea and/or aromatic amine such as aniline. Examples illustrate the preparation of a urea formaldehyde condensation product in the presence or absence of alkaline or acid catalysts.
