Properties of toughened degraded polypropylene with EPDM
关键字：degraded polypropylene/EPDM blends；toughness；impact-strength； tensile-strength；brittle-ductile transition
In this paper, the peroxide was used to degrade polypropylene (PP). Toughened degraded polypropylenewith ethylene-propylene-diene monomer (EPDM) and its brittle-ductile transition(BDT) of degraded PP/EPDM blendswere studied. It was found that increas...

Diethanol Ammonium-borate Based Polybetaine with Tunable UCST Phase Transition
关键字：Tunable UCST Phase Transition
A betaine-type styrene monomer with the quaternary ammonium-borate anion inner-salt pair was synthesized
through the quaternization reaction and polymerized to afford the target polybetaine of poly(4-vinylbenzyl methyl-diethanol
ammonium borate) (PVMAB). The chemical structures of the monomer and polymer were well demonstrated with 1H-NMR
and 11B-NMR spectra analysis. The thermal-sensit...

Conformational Identification and Phase Transition Behavior of Poly(trimethylene 2,6-naphthalate) α?Form Modification
关键字：PTN, α?Form crystal, conformation, Phase transtion
Poly(trimethylene 2,6-naphthalate) (PTN) is one of the 1,3-propanediol (PDO)-based aromatic polyesters which has potential applications for special barrier films and
packaging due to its excellent oxygen and carbon dioxide gas barrier property. In this work, we investigated the chain conformation and phase transition behavior of poly-
(trimethylene 2,6-naphthalene) (PTN) α-form crystal with synch...

Study of the Kinetics of the Pancake-to-Brush Transition of Poly(N-isopropylacrylamide) Chains
关键字：pancake, brush, pnipam, qcm
The chemical grafting of thiol-terminated poly(N-isopropylacrylamide) (HS-PNIPAM) chains to a gold surface from a solution was investigated with a quartz crystal microbalance (QCM) in real time. The frequency and energy dissipation responses revealed that short HS-PNIPAM chains exhibit three-regime kinetics of the grafting. In regimes I and II, the HS-PNIPAM chains form pancake an...
