The crystallization kinetics of poly(L-lactide-co-rneso-lactide) were determined over a range of 0% to 9% mesolactide. The kinetics were fit to the nonlinear Avrami equation and then to the Hoffman-Lauritzen equation modified for optical copolymers. The theory was found to fit the data well. The cry

Isothermal melt crystallization of poly( L-lactide ) (PLLA) has been studied in the temperature range of 90 to 135ΠC. A maximum in crystallization kinetic was observed around 105ΠC. A transition from regime II to regime III is present around 115ΠC. The crystal morphology is a function of the degree
## Abstract This study evaluated the __in vitro__ strength retention and polymer characteristics of plates and screws made from commercially available 70:30 poly(Lβlactideβ__co__βD,Lβlactide) over a 2βyear time period. Test samples included three routine manufacturing lots each of plates (1.2 mm th
Physical aging of poly(aryl ether ether ketone ketone) (PEEKK) was investigated. Heat flow responses were measured after annealing the amorphous samples that were obtained by quenching the melt into an ice-water bath at just below the glass transition temperature. Isothermal cold crystallization of
