Abstract
Optically active polymers are of the formula ##STR1## wherein R and R.sup.1 are different from each other and are selected from the group consisting of (C.sub.1 -C.sub.20)alkyl, (C.sub.2 -C.sub.20)alkenyl, (C.sub.2 -C.sub.20)alkynyl, (C.sub.3 -C.sub.22) cycloalkyl and (C.sub.6 -C.sub.22)aryl, the alkyl, alkenyl and alkynyl further including an atom selected from the group consisting of N, O and S in the chain, the alkyl, alkenyl and alkynyl further including a substituent selected from the group consisting of (C.sub.1 -C.sub.4)alkyl and halogen atoms, the cycloalkyl and aryl further including an atom selected from the group consisting of N, O and S in the ring, and the cycloalkyl and aryl further including a substituent selected from the group consisting of (C.sub.1 -C.sub.10)alkoxy, aryloxy, halogen atoms, NO.sub.2 and NHCOR.sup.4 wherein R.sup.4 is selected from the group consisting of (C.sub.1 -C.sub.6)alkyl, (C.sub.2 -C.sub.6)alkenyl, (C.sub.2 -C.sub.6)alkynyl and (C.sub.6 -C.sub.10)aryl; R.sup.2 is selected from the group consisting of --CO--, --CO--R.sup.3 --CO--, (CH.sub.2).sub.q, --C.sub.6 H.sub.4 --, 4,4'-biphenylene and --OCNH--R.sup.3 --NHCO-- wherein R.sup.3 is selected from the group consisting of (C.sub.1 -C.sub.10)alkyl, (C.sub.2 -C.sub.10)alkenyl, (C.sub.2 -C.sub.10)alkynyl, (C.sub.4 -C.sub.20)aryl and (C.sub.3 -C.sub.20)cycloalkyl and q is from 1 to 12; m is from 1 to 10,000; and p is from 0 to m. The polymer is formed from a stereochemically pure compound.
