Abstract
Styrene-acrylic copolymers used as melt adhesives develop bond strengths which vary strongly with bond formation temperature. The variation is reversible, bond strengths of laminates reflecting the most recent temperature exposure. Loss of bond strength has been studied in samples aged at temperatures above and below the polymer glass transition, and in humid as well as dry environments. Large differences in aging rates were observed; laminates prepared at temperatures above 180°C lose strength at roughly equal rates in dry and humid environments. Laminates prepared at lower temperatures age very swiftly in the presence of water but bond strengths remain constant during aging under dry conditions. These observations are linked to different flow mechanisms which influence the viscoelastic behavior of these polymers.
