Abstract Introduction of primary covalent crosslinks into linear, segmented elastomers was followed by observing their modulus–temperature behavior. The behavior of the linear segmented polymers is explained by association of glassy segments into regions which act as filler and quasi‐crosslink. In several cases crosslinkage disrupts these regions and thereby lowers the “plateau” modulus.
