Phase transition of 5CB/DDAB/Water microemulsion: a real time investigation by means of dielectric spectroscopy
Liquid Crystal (LC) Microemulsion received much attention in the past several years. Early study on the phase behavior of LC microemulsion showed that a new phase, “transparent nematic (TN)” phase, is formed during phase transit...

High glass transition and optical transparency of novel polyimide containing 4-tert-butyltoluene moiety
关键字：Polyimides,Solubility,Optical transparency,Dielectric constant
Novel polyimide (PI) 3 was prepared from 4,4’-diaminodiphenyl-4”-tert-butyltoluene and 3,3’,4,4’-biphenyltetracarboxylic dianhydride via a one-step high-temperature polycondensation. The obtained PI 3 showed good solubility in many common solvents such as&...

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...

Effect of monomer structure on crystallization and glass transition of flexible copolyesters. J Polym Environ 2016 doi:10.1007/s10924-016-0881-5
Amorphous flexible (co)polyesters with low glass transition temperature (Tg) are very desirable in impact modification of biodegradable brittle polymers and synthesis of biodegradable elastomers. However, most flexible polyesters and binary copolyesters made from linear diacid(s) and diol(s) are crystalline polymers. In order to investigate the effect of monomer structure on the crystallization ...

35. Humidity Effects on the Wetting Characteristics of Poly(N-isopropylacrylacmide) During a Lower Critical Solution Transition
Poly(N-isopropylacrylamide) (PNIPAM) is expected to find utility in tissue engineering and drug delivery, among other biomedical applications. These applications capitalize on the intrinsic lower critical solution temperature (LCST) of the polymer: below the LCST, enthalpic gain from intermolecular hydrogen bonding between PNIPAM and water molecules dominates the solvation; above the LCST, entro...
