Nonisothermal crystallization kinetics of bio-based semi-aromatic polyamides
关键字：poly(decamethylene terephthalamide)，Nonisothermal crystallization kinetics，Biobased，Semi-aromatic polyamides
Semi-aromatic copolyamides PA10T10I and PA10T10F based on bio-based poly(decamethylene
terephthalamide) (PA10T) were synthesized by a two-step polycondensation technique. The nonisothermal crystallization of these semi-aromatic polyamides was investigated by differential scanning calorimetry. Avrami theory modified by Jeziorny and Mo equation was used to describe the nonisothermal crystalliza...

Modification of Poly(ethylene 2,5-furandicarboxylate) with Bio-based 1,5-Pentanediol: Significantly Toughened Copolyesters Retaining High Tensile Strength and O2 Barrier Property.
Poly(ethylene 2,5-furandicarboxylate) (PEF) is a biobased polyester characterized by high gas barrier properties as well as high tensile modulus and strength, but poor toughness. Toughening PEF without sacrificing its modulus, strength and gas barrier performance is a great challenge for PEF modification. In this study, high molecular weight random poly(ethylene-co-1,5-pentylene 2,5- furandicarb...

High molecular weight polyesters derived from bio-based 1,5-pentanediol and a variety of aliphatic diacids: Synthesis, characterization and thermo-mechanical properties
High molecular weight aliphatic polyesters were synthesized from biobased 1,5-pentanediol and aliphatic diacids with 4, 5, 6, 9, 10, or 12 carbon atoms via melt polycondensation. The poly(1,5-pentylene dicarboxylate)s were characterized with intrinsic viscosity, gel permeation chromatography (GPC), nuclear magnetic resonance (NMR), differential scanning calorime...

【Polymer Test-2017年夏季】In situ construction of Ag NPs in bio-inspired multilayer films for long-term bactericidal and biofilm inhibition properties
Bacteria can easily adhere on the surface of implants and subsequently form biofilm which lead to serious critical issues in the application. In the current work, poly(acrylic acid) (PAA) was firstly modified with dopamine (dopa)into dopa-PAA and was self-assembled with poly(ethylenimine)-AgNO3 (PEI-AgNO3) into multilayer films vialayer-by-layer self-assembly technique. AgNO3 were in situ r...

Isoselective 3,4-(co)polymerization of bio-renewable myrcene using NSN-ligated rare-earth metal precursor: an approach to a new elastomer
The polymerization of bio-renewable myrcene (MY), using a cationic beta-diimidosulfonate lutetium catalyst in high activity, afforded an unprecedented isotactic 3,4-polymyrcene (PMY) with a low T-g (-42 degrees C). Based on this result, the random and block copolymerization of myrcene and isoprene (IP) resulted in novel elastomers that comprise the amorphous iso-3,4-PMY and iso-3,4-PIP sequences...

(Ind. Eng. Chem. Res. )2, 5-Furandicarboxylic acid and Itaconic acid Derived Fully Bio-based Unsaturated Polyesters and their Cross-linked Networks
A range of fully biobased unsaturated polyesters (bio-UPs) derived from 2,5-furandicarboxylic (FDCA),itaconic acid (IA), succinic acid (SA), and 1,3-propanediol (PD) were obtained via direct polycondensation. The chemical structures of the bio-UPs were identified by Fourier transfrom infrared spectroscopy and 1H NMR before they were cured together with a biobased, nonvolatile reactive diluent, g...

Layer by layer deposition of polyethylene imine and bio-based polyphosphate on ammonium polyphosphate: a novel hybrid for simultaneously improving the flame retardancy and toughness of polylactic acid
In this study, a facile approach to fabricate a novel bio-based hybrid (BBH) with core/shell structure is presented by taking advantage of plant-derived resources. The BBH developed herein comprises of an inorganic core of ammonium polyphosphate (APP), covered with an organic shell that is constructed via layer-by-layer assembly of a novel bio-based polyelectrolyte (BPE) and polyethylene imine (...

(RSC Adv.)Bio–based tetrafunctional crosslink agent from gallic acid and its enhanced soybean oil-based UV-cured coatings with high performance
The utilization of soybean oil-based UV coatings depends on the introduction of petroleum-based comonomers or crosslink agents. Thus, in this paper, a bio-based crosslink agent (GACA) for UV curable coatings was synthesized from gallic acid and its chemical structure was confirmed by FT IR, 1H NMR and 13C NMR. Crosslinked networks with high biobased content of more than 88% were obtained after c...
