Vinyl acetate based polymer latex composition, especially for adhesives

A vinyl acetate based polymer latex composition obtained by emulsion polymerization, the polymer comprising

• (i) PVOH, and
• (ii) a monomer mixture, said monomer mixture comprising
• vinyl acetate,
• pre-crosslinking monomer selected from one or more polyethylenically unsaturated compounds wherein said pre-crosslinking monomer is present in amount of less than 0.01% by weight based on the total monomer content, and which pre-crosslinking monomer is initially charged to the polymerization reaction mixture, and
• a post crosslinking monomer in an amount of 0.1 to 5.0% by weight, based on the total monomer content.

An adhesive comprising a vinyl acetate based polymer latex composition obtained by emulsion polymerization, the polymer comprising

• (i) PVOH, and
• (ii) a monomer mixture, said monomer mixture comprising
• vinyl acetate, and
• a pre-crosslinking monomer selected from one or more polyethylenically unsaturated compounds wherein said pre-crosslinking monomer is present in amount of less than 0.01% by weight based on the total monomer content, and which pre-crosslinking monomer is initially charged to the polymerization reaction mixture,
• further optionally comprising:
• a post-crosslinking monomer, up to 40% by weight of another vinylic ester, up to 15% by weight of (meth)acrylic monomer, up to 3% by weight of unsaturated carboxylic acid, and up to 20% by weight of ethylene, all percentages being based on total monomer content,
• optionally in combination with appropriate additives.
