The microwave radiation effect on the polymerization of styrene

Facile synthesis of polystyrene‐coated carbon nanotubes via microwave‐assisted in‐situ polymerization and tuning of the DC electrical conductivity and impedance characteristics

“…The average diameter of the CNTs is 43 and 73 nm for the raw sample and the microwave‐assisted synthesized nanocomposite, respectively. This may indicate that the CNTs are probably coated with polystyrene 35–39 . Coated CNTs in the microwave‐assisted synthesized samples can suggest that the reaction is initiated from the surface of the CNTs.…”

Ecological risk assessment of parent and halogenated polycyclic aromatic hydrocarbons in surface sediments from an urban river in south China

“…However, the nature of the GPC curves remained unimodal on changing the mode of heating to microwaves. The lower molecular weights obtained by microwave heating could be due to the increased initiator efficiency under microwave conditions as AIBN absorbs microwaves21, 22 that could lead to the initiation of many polymer chains simultaneously and/or fast diffusion‐controlled termination reactions. The rapid and increased amount of termination reactions could also explain the increased polydispersity and limited conversion for microwave polymerization.…”

Comparative Kinetic Study and Microwaves Non-Thermal Effects on the Formation of Poly(amic acid) 4,4′-(Hexafluoroisopropylidene)diphthalic Anhydride (6FDA) and 4,4′-(Hexafluoroisopropylidene)bis(p-phenyleneoxy)dianiline (BAPHF). Reaction Activated by Microwave, Ultrasound and Conventional Heating

“…Chia et al . [ 42 ] reported a reaction rate enhancement of 120% on microwave cure of styrene at 300 watts, under comparable reaction conditions for the thermal cure. On the other hand, Lewis presented experimental evidence that microwave irradiation enhanced imidization reaction of one poly(amic acid) by a factor of 34 at 160 °C compared with the conventional thermal process [ 34 ].…”
