“…Although the concept of three‐dimensional polymers was first reported by Stockmeyer1 and Flory2 in 1940s and 1950s, considerable attention was received only in 1990s. Further theoretical investigation on this subject came from Gordon and coworkers3 and Burchard et al4 More recent works by Müller and coworkers,5 Frey and coworkers,6 Möller and coworkers,7 Dušek et al,8 Fawcett and coworkers,9 and Galina et al10 initiated detailed discussion on the theory. The term “hyperbranched” was coined by Kim and Webster11 in the late 1980s.…”

A series of linear and hyperbranched polyester epoxies, with varied structural parameters such as kinked structure and different dendritic architectures, were synthesized by A2 + B2, A2 + B3, A3 + B2, and A3 + B3 approaches. The structures of synthesized monomers and polymers were confirmed by Fourier transform infrared, 1H NMR, and 13C NMR spectroscopic techniques. The effect of varied structural parameters on phase behavior and photoresponsive properties was investigated by using differential scanning calorimeter, thermal optical polarized microscope, UV–visible spectroscopy, photoviscosity, and refractive index studies. The transition temperatures of hyperbranched polymers were higher than that of the corresponding linear analogues. All the polymers showed nematic phase (nematic droplets) over a broad temperature range. The effect of kinked structural unit on photoresponsive property is less in both linear and hyperbranched architectures. Although the effect of architectural nature is highly considerable within the hyperbranched architectures, the polymer (HPE–33) synthesized by A3 + B3 approach showed highest rate of photocrosslinking, followed by HPE–I 32; HPE–T 32, and HPE–23, which were synthesized by A3 + B2 and A2 + B3 approaches, respectively. The findings in photoresponsive properties were further supported by molecular modeling studies. Substantial variation of refractive index (0.015–0.024) indicates that these polymers could be used for optical recording. © 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem, 2011

“…Since then, and particularly since the beginning of the nineties, over 5000 papers on the synthesis and properties of hyperbranched molecules appeared [7]. Many different me-thods of modelling the hyperbranched polymerization have also been developed [10][11][12][13]. The hyperbranched polymers can conveniently be obtained by polymerization of an AB 2 monomer (A and B stand for functional groups or sites reacting with each other).…”

A theoretical model of hyperbranched polymerization involving an AB f monomer Part II. THE AVERAGE POLYMERIZATION DEGREE AND DISPERSITY INDEX * *) Summary-A generalized theoretical model of hyperbranched polymerization of an AB f monomer was used to calculate the weight average polymerization degree (P w) and dispersity index (D M) of the resulting hyperbranched polymers. The monomer functionalities were f = 2, 4, or 6. The model derived in Part I of the series and based on the Smoluchowski coagulation equation was used. The monomer functional groups B reacted according to the first shell substitution effect principle. Both, the weight average polymerization degree and dispersity index were found to grow with conversion the faster, the higher was the monomer functionality and the more positive was the substitution effect.

“…At first, the direct synthesis of AB 2 -type monomers was extensively studied [8][9][10][11][12][13][14][15][16]. However, for many applications, the products, particularly those of high molecular weight, had too broad molecular weight distribution.…”

Random homopolymerization of an AB 2 monomer as studied by Monte Carlo methods Summary-Monte Carlo simulations were carried out to model the molecular size distribution in a hyperbranched polymerization involving a monomer of AB 2 type, where A and B were functional groups reacting with each other only. Three approaches were tested: the off-lattice percolation, classical percolations on square or cubic lattices with adjustable reaction range, and the dynamic lattice liquid (DLL) simulation. The latter was used also to investigate dependence of the average radii of gyration of hyperbranched macromolecules on the conversion.
