Sensitivity of Polymer Blends to Synchrotron Radiation.
Abstract
The sensitivity of poly(methylmethacrylate), PMMA, to x-rays is enhanced by the addition of poly(epichlorohydrin), CO rubber. The two polymers appear to be miscible over a wide concentration range. Films with 20 to 50% CO in PMMA require only 1/2 to 1/4 the exposure dose of synchrotron radiation to produce an equivalent pattern in PMMA alone. The sensitivity is confirmed by measurements of molecular weight of blends irradiated by gamma rays or electrons, a well as x-rays. Dissolution behavior of the blends also is similar to that for PMMA.
