“…The homogenous distribution and better interfacial adhesion have enhanced the tensile strength and elongation at break of the biocomposites than LDPE and LM samples. The phase morphology study of semicrystalline and crystalline polymers has usually done by POM to observe the spherulite structures [70,71]. Figure 8 exhibits the POM images of all samples.…”

Low density polyethylene‐g‐maleic anhydride‐g‐starch nanoparticle (LMNS) biocomposites have been synthesized in water medium. LMNS biocomposites were fabricated with different starch nanoparticle (NS) loadings (2, 4, 6, 8, and 10 wt%) by compression molding technique. Fourier transform infrared spectroscopy revealed ester linkage between maleic anhydride grafted low density polyethylene (LM) and NS, thereby confirming the improved compatibility of the biocomposites. Thermal analysis confirmed the chemical linkage of NS on LM chains. The wettability and surface roughness characteristics of biocomposites were evaluated by water sorption, static contact angle, and atomic force microscopy. Water sorption was improved due to the increase of NS content in samples, whereas the water contact angle and surface roughness were diminished. The load at maximum, tensile strength and percentage of elongation at break for the biocomposites were enhanced with the increase in NS content. The morphology analysis of samples revealed homogenous distribution and good interfacial adhesion. The biodegradation enhancement of samples has been revealed by fungal and soil burial tests. POLYM.

“…Acrylonitrile-styrene-acrylic (ASA) terpolymer prepared by grafting copolymerization of styrene and acrylonitrile monomers onto acrylic rubber particles was developed in the 1970s as an impact-resistance thermoplastic [9]. ASA has a similar structure with acrylonitrile-butadiene-styrene (ABS) terpolymer expect the butadiene rubber was replaced by acrylic rubber, which can resolve the physical (or chemical) aging of butadiene rubber [10].…”

Preparation of acrylonitrile–styrene–acrylate (ASA) with high gloss and superior impact properties is still challenging. Here, we developed a new strategy for the preparation of ASA resins by a selective redox initiation method based on a semi‐continuous emulsion polymerization technique. A series of ASA core‐shell impact modifiers were firstly obtained by grafting styrene (St) and acrylonitrile (AN) onto poly(n‐butyl acrylate) (PBA) seeded latexes of different sizes. The ASA core‐shell impact modifier was then used to toughen the styrene–acrylonitrile copolymer (SAN). The synergistic effects between the single particle size of the rubber phase and different particle sizes were systematically investigated, and the mechanical properties of SAN‐toughened resins at various particle sizes of the rubber phase were analyzed. The results revealed that toughened SAN with small particle sizes possessed better gloss, and the impact strength of the doped small‐particle toughened SAN was much higher than that of the single particle size toughened SAN. The ASA graft powders synthesized from large particle PBA (particle size 316 nm) and small particle PBA (particle size 99 nm), respectively, were mixed at a 50/50 ratio and blended with SAN resin, a gloss level reaching 95, and an impact performance of 275 J/m values almost twice those of a single particle size toughened SAN.Highlights Acrylonitrile–styrene–acrylate resins with an impact strength of 275 J/m and gloss of 95 were prepared. The balance between mechanical properties and gloss of acrylonitrile–styrene–acrylate resin was obtained. Polymerization was initiated at low temperature.
