## Abstract In this work, a proportionalβintegralβderivative (PID) control scheme with two different tuning methods to control the degree of degradation of polypropylene (PP) during reactive extrusion is proposed. The concentration of dicumyl peroxide is taken as the manipulated variable. The molte

A kinetic model for the free-radical-initiated molecular weight degradation of polypropylene was further developed. The model has a single variable parameter, the initiator efficiency, f . Assumptions were detailed, new comparisons with experimental data presented, and model sensitivity to the value
## Abstract __In situ__ compatibilization of polypropylene (PP) and polystyrene (PS) was achieved by combinative application of tetraethyl thiuram disulfide (TETD) as degradation inhibitor and diβ__tert__βbutyl peroxide as degradation initiator in the process of reactive extrusion. The PP/PS blends
A commercial isotactic polypropylene was degraded to increase its terminal vinylidene group concentration, and it was subsequently functionalized with maleic anhydride through the Alder Ene reaction at temperatures above 200Β°C in a co-rotating twin screw extruder. Characterization of the maleated pr
