polymers, adhesion, bonds deformation curves, crack bridged zone.

Mechanical model of adhesion polymer bonding is considered. It is assumed that bonds between different polymers are formed by bundles of molecules polymer-activator of adhesion. It is taken into account that molecules of the polymer-activator can form single-link and multi-link bonds between polymers. Deformation curves of bonds in the crack bridged zone are obtained.
