| 20110034636 | Manipulating Surface Properties of Polymer with Migrating Additives - A method of obtaining a selected surface property and attribute in a host polymer or a blend of a host polymer with other polymers by blending the host polymer or polymer blend with from 0.1 to 10% by weight of a low molecular weight molecule additive (“additive”) chemically identical to the host polymer except for having one or more cores. The cores are chemically bonded to and provide anchor points for the branches which have optionally functionalized end groups. The optionally functionalized end groups, chemistry of the core, and/or physical form of the core impart properties to the surface of the host polymer or polymer blend.
