Abstract
Disclosed herein is a polymer comprising an amorphous syndiotactic rich polyolefin comprising greater than about 50 wt % C3-C40 alpha olefins and having about 50% to less than about 80% r dyads, based on the total number of r and m dyads present in the polymer; a heat of fusion of 10 joules/g or less according to the procedure described in ASTM E 794-85; and an ash content of 1 wt % or less. A functionalized amorphous syndiotactic rich polyolefin is also disclosed, along with methods to produce and a method to use the inventive polymer.
