Figure 10.7 shows that the tensile strength is improved as polystyrene is incorporated. Data for conventional melt-blended samples (Fayt et al., 1989) are provided for comparison. We note that the ductile-to-brittle transition for our system is shifted toward much higher polystyrene content. Fayt and others have shown that conventionally prepared polyethylene/ polystyrene blends are relatively poor materials (Barentsen and Heikens, 1973 Wycisk et al., 1990). Blends of most compositions are weaker than polystyrene or polyethylene homopolymers because of the poor interfacial adhesion between the two immiscible polymers. The electron micrographs and the mechanical data for the blends described here indicate that poly-... [Pg.171]

In the case of polystyrene blends with poly(vinyl methyl ether) two phase behaviour was found for blends from various chlorinated solvents whereas single phase behaviour was found for blends from toluene The phase separation of mixtures of these polymers in various solvents has been studied and the interaction parameters of the two polymers with the solvents measured by inverse gas chromatography It was found that those solvents which induced phase separation were those for which a large difference existed between the two separate polymer-solvent interaction parameters. This has been called the A% effect (where A% = X 2 Xi 3)-A two phase region exists within the polymer/polymer/solvent three component phase diagram as shown in Fig. 2. When a dilute solution at composition A is evaporated, phase separation takes place at B and when the system leaves the two phase region, at overall... [Pg.130]

Figure 4.5 Measurements of effective Flory-Huggins x parameter for deuterated polystyrene-poly(vinylmethylether) blends (Han et al, 1988) as a function of l/T. The temperature range is typically 100-150 °C, and the numbers near each set of data indicate the volume fraction of polystyrene. The observed linear dependence on 1/r provides the physical conclusion that first-order perturbation theory is a satisfactory treatment of attractive interactions here.

The main drawback of the elastomeric co-polymers is their rather high Tg, which is always higher than LLDPE co-polymers and increases with the styrene content, reaching values above 0°C beyond 60wt% of styrene.624 In the styrene range of 20-50 mol%, the co-polymer can be either amorphous elastomeric or crystalline. This kind of crystallinity occurs when the E-S dyad is stereoregular.625 Ethylene/styrene co-poly-mers can act as compatibilizer for polyethylene-polystyrene blends.

By Chemical Modification. Stabilization by chemical pretreatment with organotins (22,23,24,25) has been discussed already. Pretreatment studies with other reagents have been reviewed briefly (22), and improved stability is now also said to result from the prior reaction of PVC with maleic anhydride (92). Kennedy s interesting work on stabilization reactions of organoaluminums (93) has been continued by a report of enhanced stability (compared with that of ordinary PVC) for poly (vinyl chloride-g-styrene) obtained from the Et2AlCl-induced reaction of PVC and styrene monomer (94). Selective destruction of defect sites seems a plausible explanation for this result (94), but improved stability has been observed also for the PVC parts of PVC-polystyrene blends (53,95,96) and for the PVC moieties of poly (vinyl chloride-g-styrene )s prepared by alternative methods (95,96,97).

Addition of AN to a level of 40% (NBR-40) destroys the phase boundaries entirely, resulting in the microheterogeneous system shown in Figure 3.10. The phase domains ( 100 A) shown in Figure 3.10 are clearly smaller than the polymer molecules themselves, yet the material is not totally compatible. Only a few cases are known in which the phase division in blends is so fine such cases include the IPN s discussed in Chapter 8 and the poly(2,6-dimethyl phenylene oxide)/polystyrene blend described in Section 9.7.1.

Blends of poly(methacrylic acid) or polystyrene with epoxidised linseed oil are prepared in solution by mechanical mixing in dimethyl sulphoxide (DMSO) or tetrahydrofuran (THF) to improve the performance of the individual components. However, blends of poly(methylacrylic acid) are not able to produce compatible systems, although different compositions (15-55 wt%) of polystyrene blends will form miscible blends. The results show an improvement in properties, including biodegradation of the miscible blends, and the systems are comparable with low density polyethylene. [Pg.194]
