Abstract:
The present invention provides a core/shell polymer particle for surface sizing of cellulosic products, wherein the core polymer and the shell polymer of the core/shell polymer particle are polymerized from monomers comprising at least 40%, by weight of monomers selected from branched C3-10-alkyl (meth)acrylate, styrene, linear C1-10-alkyl (meth)acrylate, and acrylonitrile, based on the total weight of the monomers of the core/shell polymer particle; provided that the polymer of the core/shell polymer particle comprises at least 40% by weight of branched C3-6-alkyl (meth)acrylate and at least 50% by combined weight of branched C3-10-alkyl (meth)acrylate and styrene, linear C1-10-alkyl (meth)acrylate, and/or acrylonitrile, based on the total weight of the monomers of the core/shell polymer particle.

Claim (Index 18):
A core/shell polymer particle for surface sizing of cellulosic products, wherein the core polymer and the shell polymer of the core/shell polymer particle are polymerized from monomers comprising at least 40%, by weight of monomers selected from branched C 3-10 -alkyl (meth)acrylate, styrene, linear C 1-10 -alkyl (meth)acrylate, and acrylonitrile, based on the total weight of the monomers of the core/shell polymer particle;\n provided that the polymer of the core/shell polymer particle comprises at least 40% by weight of branched C 3-6 -alkyl (meth)acrylate and at least 50% by combined weight of at least one of branched C 3-10 -alkyl (meth)acrylate and styrene, linear C 1-10 -alkyl (meth)acrylate, and acrylonitrile, based on the total weight of the monomers of the core/shell polymer particle; wherein the core/shell polymer comprises (a) a core polymer polymerized from monomers comprising at least 25% by weight, of monomers selected from branched C 3-10 -alkyl (meth)acrylate, styrene, linear C 1-10 -alkyl (meth)acrylate, and acrylonitrile; and (b) a shell polymer polymerized from monomers comprising at least 25%, more preferably at least 30%, even more preferably at least 50%, by weight, of branched C 3-10 -alkyl (meth)acrylate, based on total weight of the monomers of the core/shell polymer particle, and wherein the shell polymer encapsulates the core polymer; wherein the core polymer and the shell polymer of the core/shell polymer particle are polymerized from monomers selected from tert-butyl acrylate, n-butyl acrylate, and acrylonitrile.
