Abstract
The use of a polyalphaolefin oil or combinations of polyalphaolefin oils to modify the softening point characteristics of a tackifier and compositions containing a tackifier and polyalphaolefin oil are disclosed herein.
Claims2
A composition consisting of:
- (a) from 75-95 wt % of at least one hydrogenated tackifier comprising polycyclopentadiene resins;
- and
- (b) from 5-25 wt % PAO of at least one polyalphaolefin oil (PAO), based on the weight of the tackifier and PAO(s),
- wherein the collective at least one PAO has at least one property chosen from the group consisting of:
- (i) a Kinematic viscosity≦10.5 mm2/s at 100° C.;
- and
- (ii) a pour point≦−38° C.
