## SYNOPSIS Absorption and CD spectra of the P-P\* transition near 200 nm are calculated for helical (Pro),,, forms I and I1 with a variable proline ring conformation characterized by torsion angle X in the range -60' to 60". The spectra for poly ( P r o ) I are not sufficiently sensitive to X \*
Some rheological properties of an interpolymer complex formed in the mixtures of aqueous solutions of poly(acrylic acid) and methyl cellulose are investigated. In a diluted state, the complex exhibits polyelectrolyte properties, and in the shear field, it flows like a pure poly(acrylic acid) solutio
## Abstract The conformational transition of Form II β Form I of PolyβLβproline and the intermolecular aggregation of the product Form I during and after the transition in the HOAcβpropanol mixture solvent were studied, the ratio of HOAc:propanol being changed as 1:9, 1:6, and 1:4 v/v. For the stud
Poly-0-acetyl-hydroxy-L-proline, forms I and I1 have been studied by optical rotatory dispersion (ORD) and ultraviolet spectrophotometry in solution and in the solid state. Cotton effects of opposite sign, but not mirror images, were observed in the 250 mp region for the two forms (Form I, peak 278
