Abstract
The present disclosure provides an adhesive composition. The adhesive composition includes: A) a propylene based plastomer or elastomer (PBPE) comprising up to 15 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 0.010% to 0.030%; (iii) a density from 0.860 g/cc to 0.890 g/cc; (iv) a melt viscosity at 177° C. from 1,000 mPa·s to 15,000 mPa·s; and (v) a weight average molecular weight from 20,000 to 50,000 g/mole.
