Abstract
Official abstract text for this publication.
A method for evaluating the crosslink concentration in a crosslinked rubber is provided. The present invention relates to a method for evaluating the crosslink concentration in a crosslinked rubber by small-angle X-ray scattering or small-angle neutron scattering using measurement samples prepared by swelling the crosslinked rubber to different degrees of swelling.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for evaluating crosslink concentration in a crosslinked rubber by small-angle X-ray scattering or small-angle neutron scattering using measurement samples prepared by swelling the crosslinked rubber to different degrees of swelling, wherein the swollen crosslinked rubbers are prepared by placing the crosslinked rubber and an arbitrary amount of a solvent together in a hermetically-sealed container to allow the entire crosslinked rubber to be uniformly swollen.
