Implication

Experimental study demonstrates photocrosslinking and thermal crosslinking in maleimide-modified polystyrene, indicating versatile curing routes for polymers.

Key Points

To synthesize polystyrene functionalized with pendant maleimide groups and examine its photocrosslinking, thermal, free radical, and Diels–Alder crosslinking behavior.
Incorporated pendant maleimide groups onto polystyrene chains via a mild Friedel–Crafts reaction using N-chloromethylmaleimide.
Evaluated the rate of photocrosslinking in modified polystyrene films and solutions with and without added photosensitizers.
Tested alternative crosslinking pathways, including free radical, thermal, and Diels–Alder mechanisms.
Pendant maleimide-modified polystyrene films and solutions undergo efficient photocrosslinking upon irradiation.
Addition of photosensitizers does not appreciably change the observed photocrosslinking rate.
Functionalized polystyrene successfully crosslinks through free radical, thermal, and Diels–Alder reaction routes.
