Copolyimide molecular brushes with poly(methacrylic acid) side chains as additive to polyphthalamide membrane: Organization, physical, and transport properties

Novel composite materials were successfully developed by inclusion of copolyimide molecular brushes with poly(methacrylic acid) side chains into polyphthalamide matrix. Dense nonporous membranes from these materials were investigated using atomic force microscopy, mechanical tests, and membrane techniques. The developed membranes are promising for separation of the azeotropic methanol–methyl tert-butyl ether mixture by pervaporation.

Probing the interface structure of block copolymer compatibilizers in semicrystalline polymer blends

We investigate the interfacial structure of triblock and multiblock compatibilizers in a poly(ethylene terephthalate)-polyethylene homopolymer blend using small angle x-ray and neutron scattering. Analysis reveals multiblock copolymer's thicker interface layer and higher interfacial presence compared with TBCP, explaining their respective compatibilization efficacy. This work unveils mechanisms driving MBCP performance and highlights neutron scattering's utility in industrial polymer applications.

Composite core-double sheath fibers based on some biodegradable polyesters obtained by self-organization during electrospinning

Composite electrospun fibers were prepared from biodegradable polyesters, poly(ethylene oxide) (PEO), and beeswax (BW). The fibers consisted of outer sheath of BW, inner sheath of polyester, and PEO core. The composition of the inner sheath and of the core was affected by the ratio polyester/PEO molar masses. Fibers containing an 8-hydroxyquinoline derivative as a model drug exhibited antimicrobial activity.

Synthesis and surface modification of sunflower oil-based non-isocyanate polyurethane: Physicochemical and antibacterial properties

Sunflower oil is used as the only renewable source to successfully synthesize a non-isocyanate polyurethane. The two monomers of the synthesis are obtained by environmentally clean routes, and the polymer film obtained has good elastic properties. Its modification with antibacterial agents such as tea tree oil improves the antibacterial properties but decreases its mechanical performance.

Synthesis and properties of poly(ester imide) copolymers from 3,3′,4,4′-biphenyltetracarboxylic dianhydride, 2,2′-bis(trifluoromethyl)benzidine, and 4-aminophenyl-4′-aminobenzoate

A set of PEsI copolymers were synthesized from 4,4′-BPDA, TFMB, and APAB, and their properties were tuned by varying the monomer compositions. PEsI copolymers with >60 mol% of APAB exhibited a high Tg (>450°C), a low value of CTE (<10 ppm K−1), a low dissipation factor (<0.0032) at high frequencies, and favorable mechanical properties.

Comparative study on matrix resins in two low-density polyethylene based cable insulation materials with different voltage grades

The matrix resins of two low density polyethylene cable materials with significantly different voltage grades have highly similar molecular structures including molecular weight and its distribution, vinyl content, etc. This observation suggests that the matrix resins are not necessarily different or same for the development of the cable materials with different or same voltage grades, respectively.
