Abstract

The present invention relates to a polymer composition that includes a polymer having at least one polymer segment represented by the following Formula (I), With reference to Formula (I): M independently for each w is a residue of a monomer; φ is a residue of a mechanochromic compound having at least two reactive groups that are each independently bonded to one monomer residue M; w, independently for each z, is an integer of at least 1; and z is an integer of at least 2. The mechanochromic compound is selected from at least one of the following, and
