A novel gypsum board having improved antifungal properties is disclosed. The board comprises a gypsum core, front and back paper facings, and a polymeric antifungal agent effective at inhibiting fungal growth. A preferred polymeric antifungal agent is polyDADMAC or polyTMMC. The novel gypsum board further comprises a non-polymeric antifungal agent comprising a fluorine-containing quaternary ammonium compound. Preferred non-polymeric ammonium compounds include Tetra-n-butylammonium fluoride and Tetraethylammonium fluoride. The polymeric antifungal agent can be present in the gypsum core and/or on one or both of the paper facings. The non-polymeric antifungal agent may be encapsulated in a material or ionically associated with the polymeric antifungal agent to allow releases of the non-polymeric antifungal agent over time and/or upon exposure to moisture. Methods for preparing the aforementioned novel gypsum board are also disclosed.
Sulfonic acid fluorides are prepared by reacting sulfonic acid halides with inorganic fluorides in an organic-aqueous phase. The reaction is carried out in the presence of catalytic amounts of an amine or an onium salt.

N-benzylanilinium hexafluoroantimonates, known cationic initiators, and examined their thermal reaction. The thermal reaction produced 2- or 4-benzylanilinium salts as the major products, which resulted from the rearrangement of the benzyl group. The reaction proceeded at lower temperature with higher yield when the substituent in the benzyl group was electron donating.
