| 1. A method for improving the abrasion resistance of a plastic article, said method comprising:
(a) providing a composition comprising at least one siloxane compound and at least one thermoplastic polymeric material selected
from the group consisting of polycarbonates, co-polycarbonates, and copolyestercarbonates, wherein said siloxane compound
comprises at least one cyclic siloxane having formula (I);
 wherein “n” is an integer from 3 to 1000; and R1 and R2 are independently at each occurrence a hydrogen atom, a C1-C20 aliphatic radical, a C3-C40 aromatic radical, or a C3-C40 cycloaliphatic radical;
(b) forming an article from the composition of step (a); and
(c) exposing the article formed in step (b) to an electron beam source.
