A process for removing methacrolein from liquid phase P comprising acrylic acid as a main constituent and target product, and methacrolein as a secondary component in which the removal is effected by crystallization, the acrylic acid accumulating in the crystals formed and the methacrolein in the ...
The PP film is first hydroxylation pretreated in the protection of the high-purity nitrogen. And then ceric ammonium nitrate acting as an initiator, induce graft polymerization of acrylic acid on the hydroxylated treated PP film. Thus, carboxyl functional groups are grafted on the surface of PP ...
A study was made of kinetics of graft polymerization of acrylic acid in 5% (by volume) solution of heptane at 343°K to high-pressure powdered PE exposed to radiation in air at 295°K up to 5–200 kJ/kg. A graft copolymer was obtained containing up to 40 wt.% polyacr ylic acid. ...
In this study, we report about the synthesis of such NPs by low-pressure low-temperature pulsed plasma polymerization of acrylic acid. Gas aggregation cluster source was adapted to operate plasma with a constant pulse period of 50 μs and with varying duty cycle. The NPs were produced with ...
