Abstract

The instant invention relates to oligo- and poly-carbonates terminated with silicon containing groups which are useful as reducers of surface energy for organic materials such as polycarbonates, polyesters or polyketones or their mixtures, blends or alloys. Polymers with such reduced surface energy possess self-cleaning, anti-soiling, anti-graffiti, oil resistance, solvent resistance, chemical resistance, self-lubricating, scratch resistance, low moisture absorption, dirt pickup resistance, slip properties and a hydrophobic surface; and display anti-adhesion properties against proteins and against microorganisms such as for example, bacteria, fungi and algae.
