Grafting lignin models to polystyrene by imine links

The synthesis of oligolignols grafted on polymer (LFP) was engaged in order to further study thr properties and the biodegradation mechanisms of the d ifferent lignin sub-units in conditions more similar to those involved in t he natural polymer. Simplified lignin models were grafted hy an imine or am ino link to a 1% amino ethyl polystyrene resin without any protection of th e hydroxyl functions, Infrared was used to characterize the supported model s.
