Abstract
Disclosed are aqueous compositions suitable for use as binders or adhesives in carpet products. Such compositions, prior to being applied to carpet substrates and cured, comprise vinyl ester/ethylene copolymer dispersions, along with other optional comonomers. The compositions are made by a continuous emulsion polymerisation that utilises a continuous loop reactor with a secondary line section. Carpet products which utilise such coating compositions to provide binder and/or adhesive layer within the carpet are also disclosed.
