“…Obviously, the tacticity of the polymer is inherently important to its applications. Pure isotactic PMMA have T g about 51 °C, whereas for syndiotactic PMMA T g is near 130 °C . Thus, syndiotactic PMMA via metal mediated polymerization is highly desirable for improved optical applications.…”

A series of late transition metal complexes, [(bpma)Co(μ–Cl)Cl]2, [(bpma)Cu(μ–Cl)Cl]2, [(bpma)Zn(μ–Cl)Cl]2 and [(bpma)Cd(μ–Br)Br]2 (where bpma is 4‐bromo‐N‐((pyridin‐2‐yl)methylene)benzenamine) have been synthesized and structurally characterized. The X‐ray structures of dimeric complexes [(bpma)M(μ–X)X]2 (M = Co, Cu and Zn, X = Cl; M = Cd, X = Br) showed a distorted 5‐coordinate trigonal bipyramidal geometry involving two nitrogen atoms of N,N‐bidentate ligand, two bridged and one terminal halogen atoms. The complex [(bpma)Cu(μ–Cl)Cl]2 revealed the highest catalytic activity for the polymerisation of methyl methacrylate in the presence of modified methylaluminoxane with an activity of 9.14 × 104 g PMMA/mol·Cu·h at 60 °C and afforded syndiotactic poly (methylmethacrylate) (rr = 0.69).

“…In addition to morphological effects, such as size and perfection of the crystalline regions, the major reason of the melting point depression is attributed to the classical effect of a reduction of the PVF2 activity in the amorphous phase by a miscible component, i.e. to the thermodynamic interaction between the two polymers [2,5,6,9]. When the content of PMMA reaches 30%, only one endothermic peak is observed.…”

“…used polystyrene‐ co ‐poly(methyl methacrylate) random copolymers and poly(methyl methacrylate) (PMMA) as a compatibilizer of PVDF/polystyrene immiscible blends. PVDF and PMMA are miscible in the amorphous state and have been studied using various techniques . In an A‐ b ‐B/C diblock copolymer/homopolymer system, when A block and B block are immiscible but miscible with homopolymer C, the A block can form a microdomain contingent on the concentration .…”

A polydimethylsiloxane‐block‐poly(methyl methacrylate) (PDMS‐b‐PMMA) diblock copolymer was synthesized by the atom transfer radical polymerization method and blended with a high‐molecular‐weight poly(vinylidene fluoride) (PVDF). In this A‐b‐B/C type of diblock copolymer/homopolymer system, semi‐crystallizable PVDF (C) and PMMA (B) block are miscible due to favorable intermolecular interactions. However, the A block (PDMS) is immiscible with PVDF and therefore generates nanostructured morphology via self‐assembly. Crystallization study reveals that both α and γ crystalline phases of PVDF are present in the blends with up to 30 wt% of PDMS‐b‐PMMA block copolymer. Adding 10 wt% of PVDF to PDMS‐b‐PMMA diblock copolymer leads to worm‐like micelle morphology of PDMS of 10 nm in diameter and tens of nanometers in length. Moreover, morphological results show that PDMS nanostructures are localized in the inter‐fibrillar region of PVDF with the addition of up to 20 wt% of the block copolymer. Increase of PVDF long period by 45% and decrease of degree of crystallization by 34% confirm the localization of PDMS in the PVDF inter‐fibrillar region. © 2018 Society of Chemical Industry
