Abstract
The present disclosure provides a composition. In an embodiment an adhesive composition is provided and includes A) a propylene based plastomer or elastomer (PBPE) comprising up to 10 wt % units derived from ethylene and having (i) a Koenig B-value less than 1.0; (ii) a total unsaturation per mole of propylene from 0.01% to 0.03%; (iii) a density from 0.870 g/cc to 0.890 g/cc; (iv) a melt viscosity at 177° C. from 800 mPa·s to 11,000 mPa·s; and (v) a weight average molecular weight from 20,000 to 50,000 g/mol; B) a tackifier; and C) a wax.
