Patent ID: 8318867

Claim:
An admixture comprising a base polymer selected from polypropylene and polyurethanes admixed with a surface modifier having a structure according to wherein (i) A is a soft segment selected from poly(diethylene glycol)adipate (PEGA), polytetramethylene oxide (PTMO), poly(ethyleneglycol)-block-poly(propyleneglycol))- block-poly(ethylene glycol), or polydimethylsiloxane block copolymer (C22); (ii) B is a hard segment comprising a urethane trimer or biuret trimer formed from hexamethylene diisocyanate (HDI) biuret trimer, isophorone diisocyanate (IPDI) trimer, or hexamethylene diisocyanate (HDI) trimer, and B′, when present, is a hard segment comprising a urethane; and (iii) each G is a surface active group comprising polyfluoroalkyls; wherein n is an integer from 0 to 10; and wherein (i) said surface modifier has a thermal degradation temperature of at least 200° C.; and (ii) said admixture is formed by mixing said surface modifier with said base polymer to form a mixture and annealing said mixture; and wherein when the base polymer is polypropylene, A is a soft segment selected from polymethylsiloxane block copolymer (C22) and poly(ethyleneglycol)-block-poly(propyleneglycol)-block-poly(ethyleneglycol).
