Abstract
A synthetic resin emulsion containing an acetoacetylated polyvinyl alcohol as a protective colloid, which has improved properties such as water resistance, freeze-thaw stability, stability at low temperatures, adhesive property and high viscosity even in low solid content. The emulsion is useful for various purposes such as adhesive, paper treating agent, paint, fiber and textile treating agent and cement modifier.
Claims9
An aqueous emulsion of a synthetic resin containing an acetoacetylated polyvinyl alcohol as a protective colloid, wherein the acetoacetyl content of the acetoacetylated polyvinyl alcohol is from 0.05 to 15% by mole and the residual acetyl content of the acetoacetylated polyvinyl alcohol is from 0.1 to 15% by mole.
An adhesive which comprises an aqueous emulsion of a synthetic resin containing an acetoacetylated polyvinyl alcohol as a protective colloid, wherein the acetoacetyl content of the acetoacetylated polyvinyl alcohol is from 0.05 to 15% by mole and the residual acetyl content of the acetoacetylated polyvinyl alcohol is from 0.1 to 15% by mole.
A treating agent for fiber and textile which comprises an aqueous emulsion of a synthetic resin containing an acetoacetylated polyvinyl alcohol as a protective colloid, wherein the acetoacetyl content of the acetoacetylated polyvinyl alcohol is from 0.05 to 15% by mole and the residual acetyl content of the acetoacetylated polyvinyl alcohol is from 0.1 to 15% by mole.
A paint which comprises an aqueous emulsion of a synthetic resin containing an acetoacetylated polyvinyl alcohol as a protective colloid, wherein the acetoacetyl content of the acetoacetylated polyvinyl alcohol is from 0.05 to 15% by mole and the residual acetyl content of the acetoacetylated polyvinyl alcohol is from 0.1 to 15% by mole.
A paper coating material which comprises an aqueous emulsion of a synthetic resin containing an acetoacetylated polyvinyl alcohol as a protective colloid, wherein the acetoacetyl content of the acetoacetylated polyvinyl alcohol is from 0.05 to 15% by mole and the residual acetyl content of the acetoacetylated polyvinyl alcohol is from 0.1 to 15% by mole.
A cement modifier which comprises an aqueous emulsion of a synthetic resin containing an acetoacetylated polyvinyl alcohol as a protective colloid, wherein the acetoacetyl content of the acetoacetylated polyvinyl alcohol is from 0.05 to 15% by mole and the residual acetyl content of the acetoacetylated polyvinyl alcohol is from 0.1 to 15% by mole.
