摘要：

Optical activity of a helical polymer, poly-L-lactic acid, was studied by using x-rays and HAUP methods. Gyrations depend considerably on the drawing actions. From the relation between gyrations and drawing ratios, the gyration tensor components are determined as g(1)=(-2.7 +/- 0.5) x10(-4) and g(3)=(8.3 +/- 0.2) x 10(-2). It is striking that a helical polymer like this material produces huge gyration along the helical chain.
