Abstract

The present invention relates to a copolymer composition comprising 5-95 pphwm of vinyl acetate and 95-5 pphwm of vinyl 3,5,5-trimethylhexanoate, wherein the corresponding 3,5,5-trimethylhexanoic acid has a content of the 3,5,5-trimethylhexanoic acid isomer of at least 88% by weight.Said copolymer is composed and synthesized so as to be useful in the formulation of binders for fibrous substrates such as woven or nonwoven products, paints, adhesives for porous or non-porous substrates, construction cementitious compositions, redispersible powders.
