Thermo- and pH-responsive Behaviors of Aqueous Poly(acrylic acid)/Poly(4-vinylpyridine) Complex Material Characterized by ATR-FTIR and UV-Vis Spectroscopy
A novel thermo- and pH- responsive poly(acrylic acid) (PAA)/poly(4-vinylpyridine) (P4VP) aqueous material with an upper critical solution temperature (UCST) was developed in this study. It was found that the formation of the aqueous complex material was caused by the deprotonation of pyridinium groups of P4VP molecules and consequent hydrogen bonding formation between pyridine and carboxyl...

High Molecular Weight Poly(butylene succinate-co-butylene furandicarboxylate) Copolyesters: From Catalyzed Polycondensation Reaction to Thermo-mechanical Properties.
Novel potentially biobased aliphatic−aromatic copolyesters poly(butylene succinate-co-butylene furandicarboxylate)
(PBSFs) in full composition range were successfully synthesized from 2,5-furandicarboxylic acid (FA), succinic acid (SA),
and 1,4-butanediol (BDO) via an esterification and polycondensation process using tetrabutyl titanate (TBT) or TBT/La(acac)3
as catalyst. The copolyesters...

High molecular weight polyesters derived from bio-based 1,5-pentanediol and a variety of aliphatic diacids: Synthesis, characterization and thermo-mechanical properties
关键字：Biobased polymers, Biodegradable polymers, Poly(1,5-pentylene dicarboxylate)s, Thermal property, Mechanical property
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...

Poly(L?lactic acid)-block-poly(butylene succinate-co-butylene adipate) Multiblock Copolymers: From Synthesis to Thermo-Mechanical Properties
关键字：biodegradable, multi-block copolymer, chain extension, chain coupling
Multiblock copolymers poly(L-lactic acid)-block-poly(butylene succinate-co-butylene adipate)s (abbr. P(LLA-mb-
BSA)s) are synthesized via a polycondensation/chain extension/coupling method using binary chain extenders. A poly(L-lactic acid) (PLLA) prepolymer synthesized via direct melt polycondensation of L-lactic acid is rapidly chain extended with a bis (2-oxazoline) to form hydroxyl t...
