Vesiculated polymer granules |
摘要 |
Vesiculated granules of cross-linked carboxylated polyester resin prepared by the free radical polymerization of a dispersion of an ethylenically unsaturated monomer, a carboxylated unsaturated polyester resin having an acid value of from 5-50 mg KOH/g and an alkyl acryloyl derivative. Aqueous compositions comprising the granules are used in conjunction with fibrous cellulosic or non-cellulosic materials for the preparation of paper containing the vesiculated polymeric granules dispersed therein. The paper has improved optical opacity.
