Poly(ethylene-alt-maleic acid), PEMAc, is a linear polymer that, along with its isomer polyacrylic acid, has the highest carboxylic acid content of any polymer. The goal this work was to elucidate mechanisms that control amount PEMAc permanently fixed on pulp fibers after impregnation dry dilute solution followed by drying/heating (curing). Two which cellulose were discovered, chemical, and phy...

Grafting is an ancient agricultural technique that frequently used to enhance the performance of horticultural plants, including vegetables and woody fruit trees. For successful grafting, genotypes compatible scion (the upper part) rootstock lower must interact. Molecular signals, nutritional hormonal proteins, messenger RNAs (mRNAs), are known be transferred from vice versa. Nonetheless, there...

Graft copolymerization of acrylic acid (AA) onto Poly(ethylene terephthalate) (PET) fabrics with the aid of benzoyl peroxide was carried out. The effect of polymerization parameters on the graft yield was studied. Percent grafting was enhanced significantly by increasing benzoyl peroxide (BP) concentrations up to 3.84 g/lit and then decreased upon further increase in initiator concentration. Pr...

To develop low-cost and environmentally friendly polymeric materials for enrichment, separation, and remediation of metal ions from water, graft copolymers based on cellulose extracted from pine needles were synthesized by grafting of 2-hydroxy methacrylate (HEMA) alone and with comonomers acrylic acid, acrylamide, and acrylonitrile by benzoyl peroxide initiation. The effects of change in conce...

The thermal stress caused by high temperatures on cut rose flowers grown in greenhouses is a major environmental impact that reduces the yield of growing during summer. To confirm resistance grafted to high-temperature stress, roses were greenhouse summer season and analyzed for yield, quality, root activity, photo-physiological characteristics. A morphological change was observed stomata flowe...

Grafting terminally functionalized polypropylene (PP) to nanofillers provides well-defined PP-based nanocomposites plausibly featured with a physical cross-linkage structure. In this paper, a series of PP-grafted silica nanoparticles (PP-g-SiO2) were synthesized by varying the number of grafted chains per silica particle, and influences of the number and the molecular weight of grafted chains w...

The BBCH (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie) scale is a system that helps producers monitor phenology by employing uniform methodology across different locations. This study aimed to evaluate the effect of scion×rootstock combinations on tomato yield and accumulated degree days for each phenological stage. A randomized block design with four repetitions treatmen...

Grafting polymerization was a valuable method for the modification of the chemical and physical properties of polymer surfaces. In this paper, the grafting of cationic vinyl monomer with quaternary ammonium groups, methacryloxyethyltrimethyl ammonium chloride (DMC), onto the isotactic polypropylene (iPP) granule was performed by suspension solid-state grafting process. The techniqu...

In this study we investigate the relationship between the Interleukin 2 (IL-2) yield produced by kidney allograft recipient's peripheral blood lymphocytes (PBL) under lectin stimulation and the occurrence of acute rejection episodes. PBL were harvested prospectively before grafting, after grafting in steady-state period, and at the onset of acute rejection episodes. In addition, we tested retro...
