We calculate, using a tube model, the enhancement of adhesive strength between a surface-attached chain and a matrix (in the glassy phase) that is polymerized in situ. The conformational relaxation caused by the change in the chains' local environment may or may not be dominated by entanglements. We conclude that in the favourable scenario of slow relaxation dynamics and rapid polymerization and subsequent quench (by glassification), the adhesive strength may be increased up to a factor (a/b) 1/3, where a is the tube diameter and b is the Kuhn length for the attached chain.
