Composites based on green high-density polyethylene (G-HDPE) and hydroxyapatite (HA) compatibilized with maleic anhydride grafted (HDPE-g-MAH) were developed in this work. The main objective was to evaluate the effects of HA HDPE-g-MAH contents mechanical thermal properties hydrolytic degradation composites through design experiments statistical analysis, as well hemolytic stability. Hydroxyapa...

Nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. Antimicrobial nanocomposite LDPE films containing ZnO nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-ZnO pulse 10% polyethylene grafted maleic anhydride (PE-g-MA), w/w pure LDPE), were p...

The filamentous fungus Byssochlamys fulva strain IMI 40021 produces (+)-byssochlamic acid 1, its novel dihydroanalogue 2 and four related secondary metabolites. Agnestadrides A, 17 and B, 18 constitute a novel class of seven-membered ring, maleic anhydride-containing (hence termed heptadride) natural products. The putative maleic anhydride precursor 5 for both nonadride and heptadride biosynthe...

Collagen was isolated from rat tail tendons and acetylated with 1-14C acetic anhydride. In situ adsorption of this collagen from a buffer solution (pH = 2.7) was measured at the interfaces to air, polyethylene and polyethylene grafted with poly(maleic acid), respectively. The kinetics of adsorption were recorded for all surfaces studied and the corresponding diffusion coefficients for collagen ...

The paper reports the results of studying the kinetics of DGEBA reactions with maleic anhydride catalyzed by N, N-dimethyl aniline (DMA). This stuffs are used as photoelastic model materials. The origination of monoester was studied separately on a model reaction of maleic anhydride with isopropyl alcohol. The subsequent reaction of epoxy groups with monoester was examined on a system of epoxy ...

Composite materials based on a polymer mixture -low density polyethylene and polybutylene terephthalate -have been obtained investigated. To improve the compatibility of two thermodynamically incompatible polymers, compatibilizer was used, which is modified with maleic anhydride. It found that compatibilization low polyethylene/polybutylene terephthalate, leads to significant change in basic ph...

Composites based on PLA with the addition of 3, 6 and 10 wt% silica, hydroxyapatite bentonite were obtained by twin-screw extrusion. Maleic anhydride grafted polyethylene was used to enhance interface interactions. The influence fillers Charpy impact strength, Rockwell hardness, tensile properties processing shrinkage investigated. Test samples 3D printing. highest strength hardness for composi...
