The values of a and aL of polymer single crystals [32-46], amorphous and crystalline drawn plastics [32,47,48] and drawn and undrawn speciality polymers [49-52] have been extensively studied in the last two decades. A brief description as a prelude to the expansivities of polymer liquid crystals, their blends and composites is discussed in the following. [Pg.217]

Polymeric materials have relatively large thermal expansion. However, by incorporating fillers of low a in typical plastics, it is possible to produce a composite having a value of a only one-fifth of the unfilled plastics. Recently the thermal expansivity of a number of in situ composites of polymer liquid crystals and engineering plastics has been studied [14,16, 98, 99]. Choy et al [99] have attempted to correlate the thermal expansivity of a blend with those of its constituents using the Schapery equation for continuous fiber reinforced composites [100] as the PLC fibrils in blends studied are essentially continuous at the draw ratio of 2 = 15. Other authors [14,99] observed that the Takayanagi model [101] explains the thermal expansion. [Pg.238]

Therefore, knowledge of the temperature and concentration dependencies of the interactions of the constituents provides important information which can be used to manipulate the properties of the polymer system. The following sections of this chapter will discuss the potentialities of reinforcing engineering plastics with special emphasis on the capabilities provided by blending with polymer liquid crystals (PLCs). A short review will be given on the present state of the art and the analytical tools available finally, a chosen example will be discussed. [Pg.256]

Molecular composites (MCs)—which are polymer liquid crystals and PLC blends. As in HCs, there is a rigid reinforcement. However, the reinforcement is at the molecular level—what applies to pure PLCs as well as to PLC-containing blends. Now, against the background just provided, and before going into details, let us compare PLCs with the most widely used type of polymers, that is EPs. Such comparisons have been made before [9,25,26,27] one can summarize them by saying that PLCs... [Pg.655]

Principles presents the same authoritative coverage as Chemistry but in 240 fewer pages. It does so by removing most of the boxed application material, thus letting instrac-tors choose applications tailored for their coaise. Moreover, several topics that are important areas of research but not central to general chemistry were left out, including colloids, polymers, liquid crystals, and so forth. And mainstream material from the chapter on isolating the elements was blended into the chapter on electrochemistry. [Pg.906]
