In this article, the existence of the squared density term is simply deduced from the general molecular interaction energy equation and is proved with four pairs of polymer/monomer; these are polystyrene/styrene, polyisoprene/isoprene, polymethyl methacrylate/methyl methacrylate, and polyvinyl acetate/...

Soft polymer microgels are fascinating systems whose peculiar properties have resulted in highly diversified applications, spanning from purely academic to the industrial domain1,2. Microgels as model soft spheres have been instrumental in shedding light on fundamental problems relating to phase transitions3...
(PEGDA-600) were prepared,respectively.By changing the monomer ratio,a series of superAbsorbent polymers copolymerized with AA,AM and AMPS as monomers and PEGDA-600 as crosslinking agent were successfully synthesized.The SAPs were characterized by Fourier transform infrared spectra(FTIR).Tea-bag ...
Monomeric resins are frequently polymerized at a temperature that is far below the desired glass transition temperature for the final polymer network. This work quantitatively investigates the relationship between the glass transition temperature (Tg), the cure temperature (Tcure), the maximum achievable...
Requirements of the high precision managed pressure drilling (MPD): This is due to reducing the differential pressure between fracture and pore pressure, i.e., narrow drilling fluid window for the deep and ultradeep drilling. Narrow drilling fluid window also poses difficulty to control well due ...

The polymers prepared with the blend showed higher storage modulus and broader viscoelastic behavior compared to those fabricated with tri-functional monomer. Thus, to achieve high fracture strength of the green body, we verified that the photo-cured polymer in the green body should have high cross...
20 Trimethylene carbonate (TMC) represents a suitable comonomer to modify PLLA for biomedical uses, since it can impart weaker acidity and higher flexibility to the polymeric chains. PTMC is a hydrophobic, amorphous and elastic polymer with a Tg of around −20 °C, usually used in ...
