Polymer Synthesis In A Centrifugal Field
A modern trend in polymeric materials is toward a prescribed variation in properties through the material. With currently available methods, the synthesis of such polymers is a complicated and tedious process, which, in addition, has the deficiency of generating the property distribution in a stepwise manner. We introduce here the perspectives and physical grounds for a new method of obtaining polymeric materials with controlled variations in properties by using a centrifugal field. The key to this method is the formation of the polymer in an inhomogeneous gravitational field, which leads to a change of its properties along the force gradient. Both characteristics of a centrifugal field are useful, namely, the magnitude of the force and the force gradient.
