Description

ABSTRACT:
A polymeric composition in pellet form comprising a tacky hot melt composition, comprising a) from about 5% by weight to about 90% by weight of a thermoplastic polymer, b) from about 0% by weight to about 65% by weight of a tackifying resin, c) from about 0% to about 50% by weight of a plasticizer, d) up to about 2% by weight of an antioxidant, and a pelletizing aid, wherein the tacky hot melt composition has some minimum amount of tackifier or plasticizer and is a pressure sensitive adhesive having a storage modulus, G', at about 25.degree. C., of less than about 5.times.10.sup.6 dynes/cm.sup.2, and each pellet has a substantially tack-free surface.
This invention further discloses a polymeric composition in pellet form suitable for molding articles. The composition comprises a tacky hot melt composition comprising at least one high molecular weight triblock copolymer of the general configuration A-B-A and a plasticizer and a pelletizing aid. The pelletizing aid substantially surrounds the tacky composition such that the molded articles are substantially free from surface tack.
A method of forming the pellets is also disclosed.
