摘要:
The instant invention relates to new compounds of the formula I wherein the general symbols are as defined in claim 1 and R1 and R2 are each independently of the other a silicon containing group. These new compounds of the formula I 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 a reduced surface energy possess an “easy to clean”, “self-cleaning” “antisoiling”, “soil-release” “antigraffiti”, “oil resistance”, “solvent resistance”, “chemical resistance”, “self lubricating”, “scratch resistance”, “low moisture absorption”, “dirt pickup resistance”, “slip properties” and “hydrophobic surface”; and antiadhesion properties against proteins and against microorganism such as for example bacteria, fungi and algae.

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.
