Abstract
The rupture of the crosslinked rubber membranes in the gel particles of impact polystyrene by ultrasonic energy has been discovered to be a novel route for the semiquantitative analysis of the grafted and occluded polystyrene of the composite. Applying this new technique, the weight‐average molecular weight of the matrix, grafted, and occluded polystyrene of a bulk‐polymerized impact polystyrene was found to be approximately the same.Keywords
