Preparation of thermoresponsive Fe3O4/P(acrylic acid–methyl methacrylate- N-isopropylacrylamide) magnetic composite microspheres with controlled shell thickness and its releasing property for phenolphthalein
In this work, Fe3O4/P(acrylic acid–methyl methacrylate–N-isopropylacrylamide) (Fe3O4/P(AA–MMA–NIPAm)) thermoresponsive magnetic composite microspheres have been prepared by controlled radical polymerization in the presence of 1,1-diphenylethene (DPE). The shell thickness of thermosensitive polymer (PNIPAm), which was on the surface of the microspheres, can be controlled by using DPE method. Th...

Preparation of Highly Cross-linked Hydrophilic Porous Microspheres Poly(N,N’-methylenebisacrylamide) and Poly(N,N’-methylenebisacrylamide-co-acrylic acid) with an Application on the Removal of Cadmium
An effective polymerization system was developed for the synthesis of highly-crosslinked hydrophilic monodispersed microspheres with both the micropores
and mesopores inside. A series of poly(N,N’-methylenebisacrylamide) (PMBA)
microspheres with the diameters ranging from 100 to 300 nm were synthesized by
distillation precipitation polymerization with N,N-dimethylacetamide (DMAC) as th...

155. Making a Supertough Flame-Retardant Polylactide Composite through Reactive Blending with Ethylene-Acrylic Ester-Glycidyl Methacrylate Terpolymer and Addition of Aluminum Hypophosphite
Biocompatible and biodegradable polylactide (PLA) composites with supertough mechanical property and sufficient flame retardancy were fabricated by employing a facile approach involving reactive blending of PLA and ethylene-acrylic ester-glycidyl methacrylate terpolymer (EGMA), with the addition of aluminum hypophosphite (AHP) as an effective flame retardant. In consideration of the balance betw...

(ACS Sustain. Chem. Eng.) Itaconic acid as a green alternative to acrylic acid for producing soybean oil-based thermoset: synthesis and properties
In this paper, itaconic acid was monomethylated with methanol to produce monomethyl itaconate, and then monomethyl itaconated epoxidized soybean oil (IESO) was obtained by melt ring-opening esterification of monomethyl itaconate with ESO. For comparison, acrylated epoxidized soybean oil (AESO) was also synthesized from ESO and acrylic acid with the same synthetic method. The chemical structures ...

[Polymer Chenistry] Tunable wettability of hierarchical structured coatings derived from one-step synthesized raspberry-like poly(styrene-acrylic acid) particles
A facile one-step method to fabricate hierarchical structured coatings whose wettability could be easily tuned from hydrophilic (water contact angle, 9.3°) to superhydrophobic (water contact angle, 154.2°) by controlling the assembly temperature without any specialized equipment or additional modification is reported. The building blocks for the coatings, hierarchically raspberry-like poly(styre...

Online Rheological Investigation on Ion-Induced Micelle Transition for Amphiphilic Polystyrene-block-Poly(acrylic acid) Diblock Copolymer in Dilute Solution
The ion-induced micellar transition is online-investigated by the
time dependence of the viscosity of the solution under shear flow for the first
time. During the morphological transition, the change in the micellar structure
can be tracked by the change in viscosity. Adding HCl or CaCl2 into preprepared
spherical micelle solution from the self-assembly of polystyrene-blockpoly(
acrylic acid) (PS1...

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...

Synthesis and characterization of pH-sensitive poly(N-2-hydroxyethyl acrylamide)- acrylic acid (poly(HEAA/AA)) nanogels with antifouling protection for controlled-release
Major challenges in the development of effective stimuli-responsive nanogels as targeted drugand gene delivery carriers are to improve biocompatibility, stability, and controlled release during systemic circulation. In this work, biofunctional nanogels based on copolymers of poly(N-2-hydroxyethyl acrylamide) (polyHEAA) and acrylic acid (AA) with controlled size and morphol...
