Abstract A non-swellable three-dimensional polymer having a component which is a residue of an optically active compound, which residue is chemically removable from said polymer to leave behind in the physical structure of said polymer a void corresponding to the size and shape of said residue of optically active compound, and a particular steric arrangement of functional groups within the void of said polymer corresponding to the chemical structure of said residue of optically active compound, the original polymer having recurring units of the formulas ##STR1## wherein A, C and D are residues bonded to B of compounds which residues are polymerizable or polycondensable and B is a residue of an optically active compound; a process for preparing such polymer and the form of such polymer containing such void and free of the residue of optically active compounds. Analogously the residue B can be an achiral component, the original polymer having recurring units of the formulas ##STR2## wherein A, C and D are residues bounded to B of compounds which residues are polymerizable or polycondensable and B is a residue of a polyfunctional, achiral compound.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A method of separating an optically active antipode from a racemate thereof which comprises contacting said racemate with a three-dimensional polymeric material comprising a polymer of an olefinically unsaturated compound or a polycondensation polymer having in its physical configuration a void whose size and shape and the arrangement of the functional groups therein correspond to the size and shape and the arrangement of the functional groups of an optically active compound, said polymeric material being operative to preferentially sorb an optically active compound whose size and shape correspond to said void when a racemate mixture thereof is passed over the three-dimensional polymeric material wherein the void of such polymeric material corresponds to the size and shape of the optically active antipode to be separated from said racemate.
Claim 2
Independent Claim
127 words
A method of separating an optically active antipode from a racemate thereof which comprises contacting said racemate with a three-dimensional polymeric material comprising a polymer of an olefinically unsaturated compound or a polycondensation polymer having in its physical configuration a void whose size and shape and the arrangement of the functional groups therein correspond to the size and shape and the arrangement of the functional groups of an optically active compound, said polymeric material being operative to preferentially sorb an optically active compound whose size and shape correspond to said void when a racemate mixture thereof is passed over the three-dimensional polymeric material wherein the void of such polymeric material corresponds to the size and shape of the optically active antipode to be separated from said racemate.
