Optically Active Poly-Propiothiolactones, presented in this article. The major part deals with the mechanism of polymerization of optically active .-substituted-.-thiolactones and specially with the study of polymerizability with respect to the character of .-substituent. Three types of monomer were used in the polymerization reactions: pa

Synthesis of Chiral Non-Racemic Dimers and Polymers Via Topochemical Reactions in Chiral Crystals; opochemical polymerization in the solid state and some comments on chiral crystals, we present the requirements for the performance of asymmetric polymerization based on -photocycloaddition. The planning and execution of two successful polymerizations of this sort are described. In the first, w

Circular Dichroism and Conformation in Copolymers with Aromatic Side Chains and in Low Molecular Wem a circular dichroism investigation on copolymers of optically active α-olefins with nonchiral vinyl aromatic monomers. Suitable structural and conformational models have been also examined with the aim of obtaining information on the contribution to the observed CD coming from the local side symme

Conformational Studies on Synthetic Polypeptides. Contribution to the Optical Activity from Side-Chtributions from peptide and side-chain chromophores. Nevertheless such investigations are essential in order to know the details of the aromatic contributions to the optical activity as related to the structure, especially in connection with aromatic Cotton effects observed in CD spectra of proteins

Conformational Dynamics of Optically Active Linear Biopolymers, more complex biological systems. A wealth of information is available on the thermodynamics of the helix-coil transition of linear biopolymers, and our understanding of the equilibrium properties of these systems in solution seems to be well established. Nevertheless, our knowledge of the rate and

Modification of Chiral Properties Due to Interaction of Polymers and Small Molecules or Ions, optically active polymers. Amylose derivatives have very different chiroptical properties compared with cellulose derivatives. Variations in glucosidic bonds and differing secondary structures are described and suggested as causes for this. The .-chlorination of synthetic optically active polyamide

Inversion of Optical Rotation of Poly(Propylene Oxide) by Solvent,observed also in the monomer or the ether of propylene glycol. The variation of rotivity of solvent seems to be caused by change of the polarizability of methyl or methylene group of polypropylene oxide due to the formation of a contact complex with aromatic solvent.
