ABSTRACT:
This invention relates to blends of substantially amorphous propylene/higher 1-olefin, 1-butene/higher 1-olefin, or propylene/1-butene/higher 1-olefin copolymers with tackifying resins which provide permanently tacky, low viscosity materials which have useful pressure-sensitive adhesive properties. The copolymers contain 40 to 60 mole % of one or more higher 1-olefins of the group 1-hexene, 1-heptene, 1-octene, 1-nonene and 1-decene and have a melt viscosity range of 10,000 to 75,000 cp. at 190.degree. C.
