Abstract
There is disclosed a synthetic resin powder comprising a polymer made from an ethylenically unsaturated monomer or a diolefinic monomer and a polyvinyl alcohol chemically bonded through a sulfide bond at an end thereof to the surface of a particle of the polymer. Although the synthetic resin powder of the present invention can be in the form of powder during transportation, it can easily be dispersed in water by adding water thereto under stirring, because it is excellent in dispersibility in water and blocking resistance. The synthetic resin powder is excellent also in film forming properties, and thus can preferably be used as an admixture for a mortar, etc.

A water dispersible synthetic resin powder composition which comprises a polymer and an antiblocking agent, said polymer being made from an ethylenically unsaturated monomer or a diolefin monomer and a polyvinyl alcohol chemically bonded through a sulfide bond at an end thereof to the surface of a particle of said polymer.
A water dispersible synthetic resin powder composition obtained by adding an antiblocking agent to an aqueous emulsion produced through an emulsion polymerization of an ethylenically unsaturated monomer or a diolefin monomer in the presence of a polyvinyl alcohol having a mercapto group and then drying the aqueous emulsion added with the antiblocking agent.
