Table 1.1 lists 26 commercially available brands of wood-plastic composite deck boards. Twenty of them are made of filled polyethylene, three of filled polypropylene, and three of filled PVC. In fact, only one brand of each of the two latter categories has established itself in the market (CorrectDeck and Boardwalk). Of ten the most sellable brands of composite deck boards (Trex, TimberTech, Fiberon, ChoiceDeck, WeatherBest, Evergrain, Monarch, GeoDeck, EverX/Latitudes, RhinoDeck) all ten are polyethylene-based products. 

Melt blending of PA-6 (or 66) with such an anhydride functionalized polypropylene causes a fast graft copolymer reaction between the polyamide and PP at the interface, which subsequently compatibilizes the blend. Some commercial polyamide/polypropylene blends may utilize such types of reactive compatibilization techniques. Properties of commercial PA/PP blends, both unfilled and glass filled grades, are shown in Tables 15.18 and 15.19. Typically, these blends... 

Ticona s COC (cyclic olefin copolymer) (Topas ) has been noted to significantly reduce the part warpage of fiberglass filled polypropylene. Commercial utility in automotive apphcations has been noted. 

All commercial polymers are compounds that have additives primarily intended as stabilizers. These additives protect the polymer from oxygen, heat, and other aspects of the environment. Many available polymer products are compounds that involve a wide range of ingredients, including commercial products such as polypropylene-based thermoplastic elastomers, polyvinyl chloride pipes, mineral-filled polypropylene, and pneumatic tire components. These compounds contain not only stabilizers but also other polymers, fillers, oils, curatives, accelerators (for curatives), and other ingredients. 

Comparing the Mori-Tanaka s average strain model with experimental data on commercial short glass fiber filled polypropylene composites. 

A compromise is to add some gelled electrolyte. Commercial cells use a porous polyethylene or polypropylene separator filled with a polymer and gel filling with a liquid electrolyte. They offer improved safety with more resistant to overcharge and less chance for electrolyte leakage. 

Thus, a brief survey of the current understanding of the molecular and super-molecular structures of common thermoplastics is presented first. This review starts with a brief description of the current state-of-the-art knowledge of the constitution, configuration, conformation and supermolecular structure of common glassy and semicrystalline thermoplastics. Later in this chapter, specific features of the structure-property relationships are discussed in greater detail for the most frequently filled thermoplastics. Effects of fillers on the structural variables in polypropylene, considered the most commercially important matrix, are especially emphasized. 

Most of the available commercial microporous membranes such as polysulfone, polyethersulfone, polyamide, cellulose, polyethylene, polypropylene, and polyvinylidene difluoride are prepared by phase inversion processes. The concept of phase inversion in membrane formation was introduced by Resting [75] and can be defined as follows a homogeneous polymer solution is transformed into a two-phase system in which a solidified polymer-rich phase forms the continuous membrane matrix and the polymer lean phase fills the pores. A detailed description of the phase inversion process is beyond the scope of this section as it was widely discussed in Chapters 1 and 2 nevertheless a short introduction of this process will be presented. 

Generally, nanomaterials as flame retardants do not have commercial applications. Data obtained are commonly recognized as preliminary, and they are described here just as preliminary as well. One more example of such data is a study of heat release and char formation (in per cent units) at burning of polypropylene filled with magnesium hydroxide (5 pm, 1 pm particles, and nanoparticles) (Table 14.9). 

Pore-filling MIP composite membranes had been first prepared by Dzgoev and Haupt [100]. They casted the reaction mixture into the pores of a symmetric microfiltration membrane from polypropylene (cutoff pore size 0.2 pm) and performed a cross -linking copolymerization of a functional polyacrylate for imprinting protected tyrosine. Hattori et al. [101] had used a commercial cellulosic dialysis membrane (Cuprophan) as matrix and applied a two-step grafting procedure by, (i) activation of the cellulose by reaction with 3-methacryloxypropyl trimethoxysilane from toluene in order to introduce polymerizable groups into the outer surface layer, (ii) UV-initiation of an in situ copolymerization of a typical reaction mixture (MAA/EDMA, AIBN) for imprinting theophylline.
