Abstract: This invention relates to blends of polyesters and substantially amorphous polyolefins such as amorphous polypropylene. Even small amounts of substantially amorphous polypropylene (5-10 weight percent) substantially lowers the melt viscosity of polyesters at application temperatures and reduces the temperature required for application of the adhesive blend without deleteriously affecting the bond strengths normally achieved on many substrates including fabrics, plastics, and metals. Blends of polyesters and 5-10% substantially amorphous polyolefins are also non-tacky and can be pelletized and used as pellets without difficulty.

These new adhesives can be readily applied to substrates such as tape by means of conventional hot-melt coating equipment and thereby eliminate the solvent pollution problems associated with the application of current solvent-based pressure-sensitive adhesives. Our hot-melt coated tapes generally have pressure-sensitive adhesive properties at least equivalent to those of solvent coated pressure-sensitive tapes.
