ABSTRACT:
A method for evaluating rubber is provided which can evaluate the degree of crosslinking of a crosslinked rubber product within a short period of time without performing any specific treatment. In the above method, the amount of energy shift of the peak (such as the peak of C12p3/2 of chlorinated butyl rubber) of a constituent element of the rubber is measured by photoelectron spectroscopy, and the degree of crosslinking of the rubber is evaluated from the amount of energy shift. In addition, a method for manufacturing a rubber product is also provided which includes the steps of measuring the amount of energy shift of the peak of a constituent element of the rubber product by a photoelectron spectrometer which is installed in a manufacturing line and then feeding back measurement result to adjust heat molding conditions so as to obtain a desired degree of crosslinking.
