“…Biodegradation studies showed that the starch component was biodegradable but EPMA and SMA were not affected. Bhattacharya et al [24] also studied blends of starch (70 wt%) with EVAMA, HDPEMA, and EMA. Tensile and flexural strength and ultimate elongation of these blends with maleated plastics increased significantly over that of composites containing unmodified plastics.…”

International audienceThe North American market for biodegradable plastics in 2005 was estimated to be around 60 million pounds (27 kt). Starch-based polymer blends were expected to account for 30 million pounds (14 kt) with significantly lower growth rates than other biodegradable polymers such as polyesters. The main hurdle in the growth of starch-based products is the thermodynamic immiscibility and non-wetting of starch with other polymers which leads to serious deterioration of mechanical properties at >25–30 wt% starch. Higher amounts of starch in the blends entail adding suitable functional groups on starch and other polymers in the blend to make them more compatible. The primary challenge is to develop fast reaction chemistries that can be transformed into viable processes and integrated into existing process lines with economically viable formulations. This article briefly reviews some of the most promising chemistries available for the reactive extrusion of starch-based polymer blends (biodegradable/non-biodegradable)

“…Influence of the PE type on water absorption of PE=starch was shown in paper [17]. It was stated that the water absorption rate was lower in LDPE=starch blends than in HDPE= starch blends.…”

Materials used in the research are low density polyethylene (LDPE) pure and in the composites with glycerin-modified starch (S) of various content.The aim of the present research was to specify the effect of UV radiation on a stability of the LDPE=S composite by analyzing FTIR spectra and discussing kinetics of photolysis.It was found that the modified starch protected LDPE in the LDPE=S composites against UV radiation. A decrease of rate constant k of LDPE photodegradation was reported.Results of water adsorption measurements of the composites are presented in the form of water adsorption kinetic curves and adsorption isotherms which were described well by the GAB model.

“…[13,14] More recently, similar functionalization has been investigated on biodegradable polymers such as maleation of poly(ecaprolactone). [15][16][17][18][19][20][21][22][23][24][25][26][27] Over the past years, talc as a hydrophobic and an inexpensive filler has driven an intense investigation in the reinforcement of polymers such as PP. [28] The unique characteristic features of talc are its softness, lubricity (due to weak van der Waals forces holding the silicate layers together, see hereafter), excellent wetting, and dispersion properties.…”

New talc/PBAT hybrid materials were prepared through reactive extrusion. First, PBAT was free‐radically grafted with MA to improve the interfacial adhesion between PBAT and talc. Then, the resulting MA‐g‐PBAT was reactively melt‐blended with talc through esterification reactions of MA moieties with the silanol functions from talc. Sn(Oct)2 and DMAP were used as catalysts. Interestingly, the tensile properties for these compatibilized composites were improved due to a better interfacial adhesion between both partners. XPS showed the formation of covalent ester bonds between the silanol functions from talc particles, and the MA moieties grafted onto the polyester backbones.magnified image
