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.

Compatibilization of PLA/starch composite with electron beam irradiation in the presence of a reactive compatibilizer

Advanced Composite Materials, 2013
The aim of this study is to improve the compatibility of poly (lactic acid) (PLA)/starch composite by electron beam irradiation in the presence of glycidyl methacrylate (GMA) as a reactive compatib...

Effect of reactive compatibilization on droplet coalescence in shear flow

Journal of Non-Newtonian Fluid Mechanics, 2007
Abstract The evolution of the morphology of blends of polyethylene and polyamide with a droplet–matrix morphology, generated by transient shear flows, has been determined using a method based on quenching following deformation of the samples kept between the parallel plates of a rheometer.

Compatibilization of starch–polyester blends using reactive extrusion

Polymer Engineering & Science, 2006
AbstractMaleic anhydride (MA) and dicumyl peroxide (DCP) were used as crosslinking agent and initiator respectively for blending starch and a biodegradable synthetic aliphatic polyester using reactive extrusion. Blends were characterized using dynamic mechanical and thermal analysis (DMTA).

Evaluation of isocyanate functional groups as a reactive group in the reactive compatibilizer

Journal of Applied Polymer Science, 2003
AbstractReactive compatibilization of an isocyanate (NCO) functional group as a reactive group was investigated. Five kinds of reactive polymers were prepared through solution graft polymerization of low‐density polyethylene (LDPE) copolymerized with acrylic acid (AA), maleic anhydride (MAH), glycidyl methacrylate (GMA), and masked and naked NCO ...

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/

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/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.

Reactive compatibilization of aliphatic polyamides with functionalized polyethylenes

Polymer, 1997
The grafting efficiency on different nylons (6, 11, 12, 6,10 and 6,12) of ethylene-glycidyl methacrylate copolymer (PE-g-GMA) and ethylene-ethyl acrylate copolymer at a composition of 85/15, when meltmixed under optimum conditions, was investigated. Two of these nylons, 6 and 11, were selected to be studied in the complete composition range.

The role of lubricants in reactive compatibilization of polyolefin blends

Macromolecular Symposia, 2001
Reactive compatibilization using liquid polybutadienes and dialkyl peroxides was studied in model low-density polyethylene/polypropylene (4/1) blends and the commingled waste of composition similar to these blends. The influence of three types of lubricants (Ca stearate, stearic acid - Loxiol G20 and paraffin - Loxiol G22) on the structure and ...
