THE EFFECTS of PLASTICIZERS ON CRYSTALLINITY, PERMEABILITY

All plasticizers significantly (α= 0.05) increased oxygen (O 2 P) and water vapor permeabilities (WVP) of the films as compared to that of unplasticized MC, with PEG 400 having the greatest effect on O 2 P and G having the greatest effect on WVP. With the exception of PG, all plasticizers decreased the tensile strength of MC films, with PEG

Nonisothermal crystallization kinetics of poly - DeepDyve

Poly(lactide), a bio‐based aliphatic polyester, is a subject to large research effort. One point of optimization is the acceleration of its crystallization kinetics to promote crystallinity under nonisothermal polymer processing conditions by means of compounding with nucleating agents and plasticizers. The nonisothermal crystallization kinetics of neat and formulated poly(L,D‐lactide

DSC, X-ray diffraction (XRD), and dynamic storage modulus results proved that the crystallization rate and crystallinity of HQ/RS-PEN increased significantly under the shear field. The crystallinity enhanced to a maximum of 20.1% and the melting enthalpy increased to 33.4 J/g at 310 °C under the frequency of 0.01-100 Hz for 20 min.

Effect of plasticization on heparin release from

The plasticizer depressed the burst effect for PLLA, and accelerated the kinetics of the diffusion-controlled phase. For the PLLGA 80/20, however, the plasticizer had no significant effect on the release profile or kinetics. We explain these observations in terms of hydrophilicity and crystallinity effects.

Plasticized waxy maize starch: effect of polyols and relative

The effect of the plasticizer on the glass-rubber transition temperature (T(g)) and crystallinity was characterized using differential scanning calorimetry. It was found that T(g) decreases with increasing moisture content and decreasing molecular weight of the plasticizer.

The most important finding concerning the use of the plasticizer can be found in its effect on the achieved crystallinity upon cooling at high cooling rates, as shown in Fig. 5b. At the 10% PEG level, the PLA reached nearly its maximum crystallinity even at the 80 °C/min cooling rate.
