Abstract
The surface energy of polymeric substrates is increased by the application or incorporation of novel amphiphilic block copolymers. The block copolymer additives comprise a linear hydrophilic polymer or oligomer and a random hyperbranched polymer or oligomer and is completely or partially terminated with lipophilic end groups. The polymeric articles or constructions which benefit from the application or incorporation of the amphiphilic block copolymers in the areas of anti-fog, dissipation of static electricity, paintability, dyeability, printability, wicking of moisture, adhesion and polymer compatibility include carpet fibers, composite fibers, agricultural films, nonwoven coverstock, exterior automotive bumper fascia, packaging, hygienic products, incompatible polymer blends, laminated articles and eyewear.
