COPOLYESTERS HAVING IMPROVED RETAINED ADHESION

摘要

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 wettability and superior initial adhesion and retained adhesion to various substrates. Examples for low polarity blocks are telechelic polyolefins like a hydroxyl terminated butylene/ethylene copolymer, ABA polyalkylene oxide-polysiloxane block copolymers or fluorinated telechelic polymers.
