Resin-bound hydroxyl groups were esterified by N-protected amino acids using triphenylphosphine and diethyl azodicarboxylate (Mitsunobu reaction) in tetrahydrofuran or dimethylformamide. The typical reaction time was 1 h and the yield for different amino acids varied from 65 to 100%. No racemization
## Abstract The kinetics of esterification of bisphenolβA based epoxy resin with acrylic acid in presence of triphenylphosphine has been studied. The reaction exhibits a firstβorder rate dependence with respect to [Epoxy] and [Catalyst]. A firstβorder dependence of rate with respect to [Acid] has b
