How to control molecular weight of Polymer? and is it possible that Mn almost equal to Mw in GPC results of Polymer?

20 March 2024 1 930 Report

I tried to synthesize Polymer resin, I am getting unexpected higher molecular weight peak in a GPC spectrum result, which is multiple in value then our expectations.

PGC results showing two peaks, for the unexpected peak the Mn almost equal to Mw.

want to know about such problem, why such peak appeared in GPC results.? the picture of GPC first peak attached for understanding
