The two-part monomers those can polymerize upon mixing even at temperatures in the range of -30°C to -50°C.
Dear Pushkar Kamble, usually it is the mode of initiation that decides on the polymerization temperature. Cationinc polymerization works well at lower températures with some conventional monomers. Other possibilities are also available, please check the exemple shown in the attached file. My Regards
Hi;
The polymerization of methyl methacrylate proceeds steadily in a temperature range of -40° in the presence of lithium alphamethylstyryl and lithium tert-butylate. By replacing these ingredients with lithium tert-butylate and diphenylmethyl lithium with well-defined concentrations, it is possible to polymerize methyl methacrylate at -30°C. Under these conditions, the yield is 100%. The polymerization of methyl methacrylate in the presence of a suitable initiator system such as diphenylmethylsodium and sodium tertiary butylate, can proceed at -50 °C. The yield can also reach 100%.
N-butyl acrylate can polymerize at -78 °C in the presence of n-butylsodium as an initiator for the polymerization reaction and sodium tertiary butylate.
With my regards
