摘要：
An instrument has been developed to determine the number of chain scissions and energy consumed per unit fracture area. This instrument utilizes a fine dental burr connected to a rheometer. Its motions are such that it grinds off about 4000 angstrom in height from the polymer films per pass. The first application is to partly annealed polystyrene latex films where it is shown that four regimes of fracture exist as annealing progresses.
