Factors Affecting Adhesive and Solvent Bonding

2 Factors Affecting Adhesive and Solvent Bonding 9.2.2.1 Solubility 

Solvent bonding is most effective with polymers having low intermolecu-lar forces. Amorphous polymers or polymers with low crystallinity are more soluble in most solvents. Lower molecular weight polymers and polymer molecules with less cross-linking and more branching structures are more easily dissolved in solvents. Elevated temperatures increase the solubility of all polymers. Polymers dissolve most easily in solvents of the same polarity polar polymers generally dissolve in polar solvents, and non-polar
