This work examined the use of passivation polymers in the conservation of severely damaged paper. It specifically investigated the use of this functional polymer treatment to address the issues of damage to paper caused by waterlogging, mold, and internal acidity. Several experiments were designed and conducted to examine the effects of the polymers in the conservation of papers compromised by these conditions. Paper artifacts from the Bonfire Memorabilia Collection were selected and conserved using treatment protocols that included the use of the passivation polymers. The conservation of some of the damaged papers from this culturally important site demonstrated the effectiveness of the polymer treatment in real-world conservation situations. This dissertation established that the use of passivation polymers adds strength and stability to severely damaged paper.
