FINELY-DIVIDED POLYMERIC SOLIDS HAVING IMPROVED PHYSICAL PROPERTIES

摘要

ABSTRACT OF THE DISCLOSUREFinely-divided dispersed solids are preparedby polymerizing in the presence of a free radical catalystand an organic solvent a major amount of an ethylenicallyunsaturated monomer or mixture of monomers and a minoramount of a hydroxy-terminated organic compound havingfrom one to eight hydroxylgroups, an equivalent weight offrom 500 to 10,000 and containing a polymerizable carbon-to-carbon double bond. The resulting polymeric solids areparticularly useful in the preparation of reinforcedpolymer compositions.
