Zur anionischen ε‐caprolactam‐polymerisation. Versuche über die viskosittsstabilisierungG RIGNARD compounds have been used for the anionic caprolactam polymerization to obtain a more uniform course. The polymerization processes were successful, but they followed the same rules which were observed ...
Anionische polymerisation des ε‐caprolactams mit ungesttigte gruppen enthaltenden aktivatorenSome regularities of anionic polymerization of 蔚-caprolactam in presence of new activators involving unsaturated groups (N-methacryloyl-蔚-caprolactam and N.N.-diphenylacrylamide) have been studied. The mechanism...
[Also in Division C3] Apparatus for the continuous polymerisation of caprolactam (see Division C3) comprises a vessel 4 provided with a gutter 7 around the inner wall above the liquid level to collect liquid which condenses on the wall of the vessel. Condensate is removed via line 8 to ...
regardless of the amount of monofunctional acid initially added.Ein Modell zur Simulierung der Kinetik der hydrolytischen Polymerisation von -Caprolactam mit bifunktionellen Molekulargewichtsreglern wird vorgeschlagen, um charakteristische Daten wie die Konzentrationen von Caprolactam, Endgruppen, -Amino...
To obtain high molecular weight nylon 6, the anionic polymerization of ε-caprolactam was investigated in terms of water content in monomer and concentration of catalyst (Grignard reagent; ethyl magnesium bromide) and chain initiator (monofunctional; N-a
