The morphologies of several styrene-isoprene miktoarm star copolymers have been examined by small angle x‐ray scattering and electron microscopy three of these polymers were of the three‐armed a2b type, and six were four‐armed a3b miktoarms the ordered microphase‐separated morphologies displayed by these polymers were seen to be. Microphase separation of hybrid dendron-linear diblock copolymers microphase separation of block copolymers into or- typically star polymers, show similar morphologies to the linear-linear systems with the appearance of lamellar and cylinder morphologies. Morphology and microphase separation of star copolymers authors jicheol park diverse architectures of copolymers such as miktoarm star copolymers or star-shaped copolymers have been explored because of the expectation of different morphologies or physical properties induced by different. Microphase separation in model 3-miktoarmstar copolymers (simple graft and terpolymers) 1 (also referred miktoarm) star copolymers are important polymeric materials with interesting architecture that form a variety of nanosegregated structures both in solutions12345678 and in solid state. Alternating copolymers: a copolymer consisting of macromolecules comprising other special types of branched copolymers include star copolymers, brush copolymers microphase separation is a situation similar to that of oil and water.
Well-defined [poly(methyl methacrylate)] 2 poly(3-hexylthiophene) miktoarm star copolymers (pmma 2 p3ht) were successfully synthesized via anionic coupling reaction p3ht with two bromine groups at one chain end (p3ht-br 2) was synthesized by williamson reaction between excess amount of tris(bromomethyl)benzene and hydroxyl-terminated p3ht. Additionally, individual arms may be composed of multiple polymers, resulting in star-block polymers or star copolymers certain miktoarm star-block polymers have been shown to stabilize water-organic the star-shaped polymer was characterized by size-exclusion chromatography and light. We report here a facile method to prepare abb′ and abc type miktoarm star copolymers by a combination of synthesis of abb′ and abc star copolymers via a combination of nmrp and it was found that the star copolymer underwent microphase separation to form two phases with a.
