Abstract

Upon discovering the issue that crosslinking shrinkage increases during crosslinking of acrylic rubber, the present invention was developed to address the problem of reducing the crosslinking shrinkage while maintaining good normal physical properties. In developing the present invention, it was discovered that the problem can be solved by causing a high molecular weight part and a low molecular weight part of the molecular weight distribution in acrylic rubber to have a specific distribution. Specifically, it was discovered that the problem can be solved by acrylic rubber 32-65% of which is accounted for by a part having a molecular weight of not more than 0.5 million and 3-20% of which is accounted for by a part having a molecular weight of not less than 2 million.
