Abstract
For example, a blended composition is produced first by letting a monomer composition, mainly composed of alkyl (meth)acrylate and including a compound having a plurality of polymeric groups within a molecule, contain microscopic particles, such as carbon black, having an average primary particle size in a range between 1 nm and 200 nm, and then the blended composition is polymerized. Consequently, it has become possible to produce inexpensive crosslinked elastomer having excellent physical properties, such as small creep (low creep) in compression set, tensile elongation set, etc., and excellent mechanical strength, such as tensile break strength and tensile break elongation, in a simple procedure omitting the post-crosslinking step at a high-level productivity while saving energy and time spent in the kneading step.
