Dicyclopentadiene is also polymerized with tungsten-based catalysts. Because the polymerization reaction produces heavily cross-Unked resins, the polymers are manufactured in a reaction injection mol ding (RIM) process, in which all catalyst components and resin modifiers are slurried in two batches of the monomer. The first batch contains the catalyst (a mixture of WCl and WOCl, nonylphenol, acetylacetone, additives, and fillers the second batch contains the co-catalyst (a combination of an alkyl aluminum compound and a Lewis base such as ether), antioxidants, and elastomeric fillers (qv) for better moldabihty (50). Mixing two Uquids in a mold results in a rapid polymerization reaction. Its rate is controlled by the ratio between the co-catalyst and the Lewis base. Depending on the catalyst composition, solidification time of the reaction mixture can vary from two seconds to an hour. Similar catalyst systems are used for polymerization of norbomene and for norbomene copolymerization with ethyhdenenorbomene. 

In continuous mixing, the numerous thermocouple wells on the barrel may be used as injection ports for the introduction of separate additive streams (crosslinker, curing agent, etc.) on-line. Figure 19 shows the cross-section of a hollow flighted-screw shaft together with a... 

While heroin can be smoked and inhaled in its powder form, the primary method of administration is through intravenous injection. To inject heroin, the user mixes the powder with water, heats it, suctions it into a hypodermic needle, and injects it into a muscle or directly into a vein. Once in the body, heroin acts much more rapidly than morphine, crossing the... 

The channel structure of the mixer is a simple cross, i.e. four channels which all merge at one junction [71]. A cross was preferred over a T-channel mixer since two interfaces instead of only one are initially created when the fluids are contacted. The top channel feeds one fluid, while the other fluid is injected via the left and right channels. The last, bottom channel functions as mixing and outlet zone. Squares, much smaller than the channel width, are positioned at the walls of this mixing channel and function as static mixing elements. The squares are positioned on alternate sides of the channels and at a distance corresponding to multiple square widths. 

For the horizontal variant, counter-, cross- and co-flow injection schemes are given (large arrows). The alternating streams enter the mixing channel in all cases as co-flows (small arrows) [39],...

Figure 1.159 Concentration profiles of an injected plug of Rhodamine B traveling over a four-groove structure in a micro channel at two different groove-to-channel mobilities rEOM and for an unstructured channel as reference case. This plot describes the axial broadening of the pulse signal. In addition, cross-sectional concentration profiles are given to analyze the corresponding impact on mixing [156] (by courtesy of RSC).
