Abstract
The invention concerns a crosslinked optically active three-dimensional polymer network, consisting of homochiral units of a first selector and of homochiral units of at least a second selector of different structure from the first selector, the homochiral units of the first selector comprising at least three polymerisable or crosslinkable functional groups and the homochiral units of the second selector comprising at least two polymerisable or crosslinkable functional groups, the homochiral groups being chemically mutually bound. The invention also concerns a method for making such a polymer network and its uses.
