Interfacial compatibilization

Owing to the multiple combinations involving interfacial compatibilizers and char promoter agents, including various polymers, this category of FR systems appears promising and yet able to meet industrial demand based on the association of excellent FR and mechanical properties. Moreover, the emergence of synthetic anionic clays, like LDHs, offers new possible combinations.

Branched polymers have attracted increasing interest due to their numerous and various applications originating from a large variety of available polymer topologies, compositions, or morphologies for phase separating systems, as emulsifier and interfacial compatibilizers, or for surface modification properties. Graft copolymers are one of the important... 

Miscibility between the individual polymers is the most important factor to determine the performance characteristics of a polymer blend. Mutual solubility of the phases, the thickness and properties of the interphase formed during blending and the structure of the blend are mainly dependent on the miscibility of individual polymers within a polymer. As a result, a quantitative estimation of interactions is very much important for the prediction of blend properties. Comparison of solubility parameters of individual polymers is an effective method to predict the extent of miscibility within a blend. According to the Hildebrand solubility theory, a large difference in solubility parameters (6p) of individual matrices results in immiscibility between them in the absence of any interfacial compatibil-izer [222]. Jandas et al. have reported that PLA and PHB have Hildebrand solubility parameters (6p) of 23.5 J /cm and 19.8 J Vcm which can turn out to be partially miscibile blends in between them [35]. In case of partially miscible blends, the miscibility can be controlled by compatibili-zation using proper interactables.
