One exception to the above mentioned trend in physical properties of immiscible blends is in the utilization of liquid crystal polymers as a reinforcement for a more flexible thermoplastic polymer. The fact that LCP s can act as reinforcing agents in a blend has led some workers to model the mechanical behavior of the blends using theories of composites. Thus, Dutta et al. (1990) showed that the moduli values of highly drawn melts that contain liquid crystal polymers can be treated effectively by a simple rule of mixtures. That is, the modulus of a blend is given by...

By blending these polymers, taking care to match melt viscosities and volnme fractions (see eq. 2 below), dual-phase continuity can be achieved (see Fig. 16) (59). In Figure 16a, droplets of material are dispersed in a continuous matrix, a morphology observed in rubber-toughened plastics. Figure 16b illustrates dispersed fibers, observed in liquid crystal polymers and some thermoplastic elastomers. If the fibers or cylinders are infinitely long, they exhibit one-dimensional phase continuity. [Pg.4079]

The increasing interest in liquid crystal polymer blends arises not only from the academic field, but also from industries focusing on innovation. Despite the higher cost of liquid crystal polymers, blending them with traditional thermoplastics results in some very competitive advantages compared to ordinary materials. The unique properties of the liquid crystal polymer blends make them not only remarkable objects for academic investigation, but also extremely versatile soft materials for industry. [Pg.49]

Nowhere is that fact more apparent than in blends of liquid crystal polymers (LCPs) with other thermoplastic polymers. It is not the intent of the present chapter to completely review all the work done in the area of blends which contain LCPs. Instead, that will be the focus of Chapter 5. The objective of the present discussion is to make general observations and show how those general phenomena may be applicable to other high temperature polymer blends as well. [Pg.7]
