Comb Block Polyolefins

Examples of crystallizable comb block polyolefins seem to be rare in spite of the significant opportunity they pose to explore structure-property relationships of new block topologies accessible by this route. In this talk we will focus on a new strategy for making comb block polyolefins. We will illustrate the approach using esterification of commercial ethylene acrylic acid copolymer (EAA such as Escor\texttrademark 5100; a high pressure, free radical initiated product) with three atactic polypropylenehydroxide macromonomers (aPPOH; M$_{\mathrm{n}}$ 1, 3, and 7k). The quantity of aPPOH in the products ranges from 13 to 60 wt{\%}. These pure products and selected blends containing them have been characterized. Findings from these experiments will be shared. .
