【42 RSC Advances】 Interplay between the compatibilization of polyethylene-graft-polystyrene and the composition of LLDPE/PS blends in the foaming behaviour
Polyethylene-g-polystyrene (PE-g-PS) copolymers, which were prepared by the combination of the ROMP and ATRP method, were utilized to compatibilize LLDPE/PS blends. On one hand, the effect of PE-g-PS on the morphologies of LLDPE/PS blends was investigated. On the other hand, the influences of branch length and added amount of PE-g-PS on the cell morphology of foamed LLDPE/PS blends with different ...

33. Mechanically strong plant oil-derived thermoplastic polymers prepared via cellulose graft strategy
Abstract: The design of polymers from renewable plant oils is gaining more attention within sustainable development. Most plant oils based thermoplastic polymers exhibit poor mechanical properties. In this paper, we reported the mechanically strong cellulose-graft-soybean oil copolymers, which combined two natural biomasses in one. The soybean oil-based monomers with secondary amide groups (SOM1...

Synthesis and thermoresponsive behaviors of thermo-, pH-, CO2-, and oxidation-responsive linear and cyclic graft copolymers
Rational macromolecular design allows us to construct multiresponsive architectural polymers with a potential toward multipurpose applications. This study aims at synthesis and LCST-type thermoresponsive behaviors of multisensitive linear and cyclic graft copolymers with polyacrylamide backbone and hydrophilic PEG grafts. The cloud point could be tuned by many factors, and the e?ect of cyclizati...

Graft Copolymerization of Styrene and Acrylonitrile in the Presence of Polypropylene Glycol: Modeling and Simulation of Semi-batch and Continuous Processes.
An existing kinetic model for graft free-radical copolymerization of styrene (St) and acrylonitrile (AN) in the presence of poly(propylene glycol) is extended to describe the semi-batch process and to simulate the continuous process. A good predictive ability of the model for the semi-batch process is demonstrated by comparing with experimental data, except for Mw and polydis...

15. Toughening polystyrene by core–shell grafting copolymer polybutadiene-graft-polystyrene with potassium persulfate as initiator
Core–shell polybutadiene-graft-polystyrene rubber particles with different ratios of polybutadiene core to polystyrene shell were synthesized by an emulsion polymerization using K2S2O8 as an initiator. Then the core–shell rubber particles were blended with PS to prepare PS/PB-g-PS. The rubber particles with a size of 0.3–0.5 mm could toughen polystyrene significantly....

8. Synthesis and characterization of an amphiphilic graft polymer and its potential as a pH-sensitive drug carrier
The synthesis and properties of a new pH-sensitive polymer Poly(3-caprolactone) Grafted Poly(ethylene
glycol) Based Poly(?-amino ester) (PEGAE-g-PCL) are described here. The successful synthesis of the graft
copolymer was confirmed by 1H NMR. The self-assemble behavior of the amphiphilic polymer was
investigated using pyrene as a probe. Dynamic light scattering (DLS) sho...

10. Evaluation of pH-Sensitive Poly(b-amino ester)-graft-poly(ethylene glycol) and its Usefulness as a pH-Sensor and Protein Carrier
In this study, some possible biomedical applications of a pH-sensitive and amphiphilic
copolymer as a pH sensor and protein delivery system are reported. PAE-g-PEG was used
as a pH-sensitive polymer that can exhibit a sharp pH-dependent transition. Various fluore-
scent dyes including pyrene and RITC can be used to label the pH-sensitive polymer PAE-g-PEG,
which was e...

Construction of Small-Diameter Vascular Graft by Shape-Memory and Self-Rolling Bacterial Cellulose Membrane
Bacterial cellulose (BC) membranes with shape-memory properties allow the rapid preparation of artificial small-diameter blood vessels when combined with microfluidics-based patterning with multiple types of cells. Lyophilization of a wet multilayered rolled BC tube endows it with memory to recover its tubular shape after unrolling. The unrolling of the BC tube yields a flatm...

Synthesis and characterization of cellulose nanocrystal-graft-poly(D-lactide) and its nanocomposite with poly(L-lactide)
Abstract As a popular bioplastic, poly (l-lactic acid) (PLLA) still faces some drawbacks mainly related to its low crystallization rate and heat distortion resistance. Herein, we demonstrate a facile and promising route to solve these problems by compositing PLLA with poly(d-lactide) grafted cellulose nanocrystal (CNC-g-PDLA) which can be synthesized via ring-opening polymerization of d-lactide on...
