The Effect of Double Crosslinker on Precipitation Polymerization of Poly(acrylic acid) [PDF]

علوم و تکنولوژی پلیمر, 2014
Cross-linked poly(acrylic acid)s were prepared by dual cross-linkers via precipitation polymerization method in a binary organic solvent. Polyethylene glycol diacrylate (PEGDA-400) as a long-chain cross-linker and di(trimethylol propane) tetraacrylate ...

Precipitation co-polymerization of ethylene and 2-allylanisole for preparing self-healing polymersPrecipitation co-polymerization of ethylene and 2-allylanisole for preparing self-healing polymers [PDF]

Royal Society Open Science
In this study, a mixed solvent system composed of toluene and n-hexane was used, and a scandium catalyst was employed to catalyse co-polymerization of ethylene and 2-allylanisole, successfully preparing multi-block co-polymers with self-healing property.

Biodegradation of Dental Resin-Based Composite—A Potential Factor Affecting the Bonding Effect: A Narrative Review

Biomedicines, 2022
In recent years, although resin composite has played an important role in the restoration of tooth defects, it still has several disadvantages, including being biodegraded by saliva, bacteria and other enzymes in the oral cavity, which may result in ...

Migration and transformation of the polybutadiene phase in ABS during Fused deposition Modeling: Controlling mechanical anisotropy

Materials & Design
Acrylonitrile-butadiene-styrene (ABS) is extensively utilized in Fused Deposition Modeling (FDM), yet the persistent mechanical anisotropy of printed parts remains a major obstacle. Moving beyond the conventional focus on processing parameters, this work

Synthesis of an aromatic N-heterocycle derived from biomass and its use as a polymer feedstock

Nature Communications, 2019
Aromatic N-heterocyclic compounds are important chemicals, but produced from petroleum. Here the authors show a pyridazine-based compound 6-(4-hydroxy-3-methoxyphenyl)pyridazin-3(2H)-one, used as polymer feedstocks, can be synthesized by a Friedel-Crafts

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
