Engineering analysis of the reactive extrusion of ϵ‐caprolactone: The influence of processing on molecular degradation during reactive extrusion

Journal of Applied Polymer Science, 2004
AbstractWe have observed that earlier models of the reactive extrusion of ϵ‐caprolactone (CL), which do not include a consideration of mechanical degradation, significantly overpredict the molecular weights of the product. We have performed an engineering analysis of the increase in the molecular weight and the shear‐induced reduction of the molecular ...

Reactive Extrusion for Thermoplastic Starch-Polymer Blends

2014
This chapter briefly reviews reactive extrusion developments for thermoplastic starch polymers. Then, a case study for thermoplastic starch polymer/biopolyester nanocomposite blend will be examined. In this example, maleic anhydride and dicumyl peroxide were used as cross-linking agent and initiator, respectively, for blending starch and a ...

Chemical Processes Applied To Reactive Extrusion Of Polymers

Annual Review of Materials Research, 1991
Many commercial polymers such as polyamides, polyesters, and poly­ olefins undergo a final processing step in which polymer from a reactor tank is fed to an extruder. Molten polymer is conveyed continuously by a screw or pair of screws down the hollow barrel of the extruder to an exit die from which material is extruded into fine strands.
