Abstract
The present invention provides copolyester compositions and novel methods employing such compositions. The copolymer compositions comprise a copolyester containing a low polarity block in the copolyester backbone, thereby resulting in adhesive and coating materials that exhibit improved flow and wettablility and superior initial adhesion and retained adhesion to various substrates.
