摘要：
The present invention relates to stable aqueous colloidal dipersions of sulfopolyureas and self supporting films formed from the dispersions which display good mechanical properties from about room temperature to temperatures exceeding 150.degree. C. The films of the invention, which are formed with no volatile organic compound (VOC) emissions and no post-coating chemical or ionic cross-linking, are not redispersible in water and may be used to form heat resistant abrasive articles.
