View the Complete Application at the US Patent & Trademark Office
Processes for lowering the glass transition temperature of a polymeric compound relative to the glass transition temperature of a control polymeric compound are disclosed. The methods include the formation of a precursor composition comprising precursor compounds to the polymeric compound dispersed or dissolved in a solvent system. The compounds are partially or fully cured in the presence of the solvent system, which is then substantially removed. After further curing, where necessary, the resulting cured polymeric compound is essentially free of plasticizers, but still has a decreased glass transition temperature relative to the glass transition temperature of a control polymeric compound. Articles of manufacture comprising such polymeric compounds are also disclosed.
