OLIGO- AND POLY-CARBONATES TERMINATED WITH SILICON CONTAINING GROUPS AS SURFACE MODIFIERS

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.
