Reactive Compatibilization of Polylactide/Polypropylene Blends

Industrial & Engineering Chemistry Research, 2015
Polylactide (PLA) was melt blended with either polypropylene (PP) or a polypropylene based elastomer (PBE, Vistamaxx) in an effort to improve its mechanical properties. An ethylene–glycidyl methacrylate–methyl acrylate terpolymer (PEGMMA, Lotader) was utilized as compatibilizer through coupling to the end groups of PLA. Graft copolymers formed enhanced

Reactive splicing compatibilization of immiscible polymer blends: Compatibilizer synthesis in the melt state and compatibilizer architecture effects

Polymer, 2019
Abstract Reactive compatibilization is an effective method to improve the compatibility of immiscible polymer blends. The in-situ-formed graft/block copolymers should be thermodynamically located at the interface to bridge the neighboring phases. Unfortunately, they are often pulled out of the interface because of the asymmetric molecular structures.

Reactive compatibilization of polypropylene/polyethylene terephthalate blends

Polymer Engineering & Science, 1999
AbstractThe reactive compatibilization of polypropylene/polyethylene terephthalate (PP/PET) blends by addition of glycidyl methacrylate grafted PP (PP‐g‐GMA) was studied. Two PP‐g‐GMA copolymers, containing either 0.2 or 1.2 wt% of GMA, were used as interface modifiers.

A reactive compatibilizer for polydimethylsiloxane-polyurethane composite coating

Progress in Organic Coatings, 2021
Abstract A novel reactive compatibilizer (PMHS-g-AEM) was prepared via grafting allyloxy (polyethylenene oxide) methyl ether (AEM) onto poly(methylhydrosiloxane) (PMHS) and its structure was characterized by 1H NMR and FTIR. Meanwhile, the compatibilization of PMHS-g-AEM for two components: nonpolar polydimethylsiloxane (PDMS, originated from ...

Compatibilization of polymer blends by reactive processing

Polymer Engineering & Science, 1991
AbstractThis review examines some recent developments in the field of reactive compatibilization of polymer blends by melt processing in extruders and intensive batch mixers. Three routes to reactive compatibilization are considered, namely, the use of suitably functionalized blend constituents, the incorporation of polymeric compatibilizers, and the ...

Reactive compatibilization of PLA/TPU blends with a diisocyanate

Journal of Applied Polymer Science, 2013
AbstractThis study focuses on the compatibilization of poly(lactic acid) (PLA)/thermoplastic polyurethane (TPU) blends by using 1,4 phenylene diisocyanate (PDI) for the first time, as the compatibilizer. Because of the potential interactions of diisocyanates with OH/COOH, they are useful for reactive processing of PLA/TPU blends in the melt ...

Enhancement in interfacial reactive compatibilization by chain mobility

Polymer, 2014
Abstract This study investigates the role of polymer chain mobility, through the addition of a plasticizer, N-butylbenzene sulfonamide (BBSA), on the overall blending dynamics and interfacial copolymer chain formation in the reactive blending of brominated poly(isobutylene-co-p-methylstyrene) (BIMSM) and polyamide (PA).

Reactive compatibilization of polypropylene

1999
Polymers may be chemically modified in order to meet specific cost/ performance/processability characteristics. Modification may involve single polymers or mixtures of two or more polymers. Reactive modification of single polymers may be accomplished through a variety of reagents or through radiation.

Reactive compatibilization and fracture behavior in nylon 6/VLDPE blends

Journal of Applied Polymer Science, 1999
A physical and mechanical characterization of blends of Nylon 6 (PA6) and very low density polyethylene (VLDPE), functionalized with maleic anhydride (MA) or diethylmaleate (DEM) is reported. The functionalization of VLDPE with MA and DEM was performed by reactive extrusion in a twin-screw (Berstoff) extruder in the presence of dicumylperoxide. The PA6/

Reactive Compatibilization in Nano-Silica Filled Polypropylene Composites

Solid State Phenomena, 2007
Nano-sized silica was pre-grafted with poly(glycidyl methacrylate) (PGMA) by solution free-radical polymerization. When these grafted silica particles were melt compounded with polypropylene (PP), reactive compatibilization effect was perceived due to the chemical bonding between the PGMA and amine functionalized PP, which led to a significant increase
