Effect of N,N'-bis(benzoic) 1,4-cyclohexanedicarboxylic acid dihydrazide on poly(L-lactide) crystallization
Abstract
Effect of N,N'-bis(benzoic) 1,4-cyclohexanedicarboxylic acid dihydrazide (CADBH) on the crystallization of poly(L-lactide) (PLLA) was investigated. CADBH (0.4-4 wt%) was introduced into PLLA by melt mixing. DSC confirmed that PLLA crystallization depends on both CADBH content and cooling and heating rates. The minimum crystallization half-life (35.4 s) was obtained at 115ºC with 3 wt% CADBH. However, a small addition of CADBH had an unfavorable effect on PLLA transparency.
