Cellulosic diamines as reaction-incorporated fillers in epoxy composites

Cellulosic fillers have been chemically modified by attaching pendant primary amine groups (diamino propane). The modified cellulose fillers were used for curing an epoxy resin (diglycidyl ether of bisphenol A). Gel times thus obtained are much less than systems containing unmodified cellulose. The advantages from the use of such modified organic fillers are discussed. Our investigations could encourage greater utilization of renewable lignocellulosic materials as reactionincorporated fillers for polymer composites.NCL Communication No. 4908.
