Phase behavior and interfacial properties of diblock copolymer-homopolymer ternary mixtures: Influence of volume fraction of copolymers and interaction energy

Compatibilization Efficiency of Additives in Homopolymer Blends: A Dissipative Particle Dynamics Study

“…They attributed the reduction of interfacial tension by the addition of compatibilizers to the decreasing number of unfavorable contacts. The ratio between chain extension, parallel and perpendicular to the interface, has also been proven to be significantly correlated with the compatibilization efficiency of copolymers. ,,, However, relationships between the interfacial tension and the above parameters are restricted to selected types of copolymers only, mainly symmetric diblocks. It is, therefore, desirable to find one critical parameter, which can be used to universally correlate the variation of interfacial tension with the molecular architecture of many different copolymer additives.…”

Preparation and compatibility mechanism study of the polyurethane-polysiloxane copolymer with tunable polysiloxane content for TPU/MVQ blends with comfortable texture

“…Because the molecular weight of copolymer compatibilizer will affect the final dispersion and migration of the compatibilizer in blends, the molecular weight of PU-PDMS compatibilizer plays a key role in controlling the compatibility effect. 22,41–45 The molecular weight of PU-PDMS was controlled by changing the feeding ratio of PDMS/PTMG and MDI by providing excess –OH groups. As shown in Table 1, the molecular weights ( M n ) of PU-PDMS compatibilizer with different PDMS contents range from 1.2 × 10 4 g mol −1 to 1.7 × 10 4 g mol −1 , and the value of dispersibility is about 2, which indicated the effective control of PU-PDMS structure and simultaneous shortening of the fluctuation range of the molecular weight, which is beneficial for improving the compatibility effect.…”
