Polystyrene binary-grafting

Fig. 7. Investigating phase segregation and formation of patterns in multicomponent polymer brushes as observed by AFM. In this case, glassy and rubbery binary components of grafted pol3rmethacrylate (PMA) and fluorinated polystyrene copol3rmer (PSF) were sensitively imaged and differentiated between topc aphy (left), phase imaging (right), and glassy (top) and rubbery (bottom) states of the binary brushes. Dimensions at 5 x 5 /rm. From Ref. 107.

High Impact Polystyrene is properly treated as a ternary system and not as a binary blend of polystyrene and polybutadiene. The third component is graft copolymer (i.e., styrene grafted onto polybutadiene) formed during polymerization. It thus resembles the ternary systems involving block copolymers described in the previous sections. 

In this chapter, we have described the behavior of ternary systems. This includes ternary low molecular weight systems (Section 6.2). Polymers with two low molecular weight liquids (Section 6.3) binary polymer blends with a low molecular weight liquid (Section 6.4), binary polymer blends with amphiphilic molecules or block/graft copolymers (Sections 6.5 through 6.7), high impact polystyrene (Section 6.8) and ternary polymer blends (Section 6.9).
