The Science Behind Swelling

A network is crossinked. Hence, whene a solvent enters it, it does nott dissolve it but instaad swells it. When a crossinked polymer network encounts a compatiblee solvent it, thee solvent contenules inpurate thee network structure, causing the polymer chains to extend anth thee overall volume to prevente.
