“…Thanks to recent advances in polymer synthesis, mainly to the development and optimization of controlled radical polymerization (CRP) techniques, relatively facile and cheap synthetic methods for preparation of gradient copolymers are available 3–5, 8–24. and there exists a high number of experimental studies of gradient copolymers, both in bulk and in solution in these days 2, 24–41. The preparation methods, the main physical properties and potential applications of gradient copolymers were reviewed, e.g., by Beginn in 2008 42.…”

We present a computer study of the association behavior of copolymer chains with a gradient part and soluble tail of variable length. As a simulation method we use dynamic Monte Carlo simulation on a simple cubic lattice with pair interaction parameters. The solvent quality and selectivity is modeled by the variation of pair interaction parameters between nearest neighbors on the lattice. The role of the length of soluble part in the self‐assembly and its effect on the structure of aggregates was the main goal of this work. The size and structure of aggregates were analyzed using an improved topological classification method which has been developed and tested in the present study. The structure and association numbers of aggregates were compared with those of linear diblock copolymers.

“…Some GMA copolymers were also synthesized by one of the controlled radical methods, that is, atom transfer radical polymerization (ATRP) 17, 18. This method allowed researchers to obtain the well‐defined copolymers of GMA with styrene19 and butyl acrylate20, 21 using catalytic copper halide. In both cases, the GMA reactivity ratio was higher than that of the comonomer, which successfully resulted in structures with a spontaneous gradient.…”

Glycidyl methacrylate (GMA) and methyl methacrylate (MMA) copolymers were synthesized by atom transfer radical polymerization (ATRP). The effect of different molar fractions of GMA, ranging from 0.28 to 1.0, on the polymer polydispersity index (weight-average molecular weight/number-average molecular weight) as the indicator of a controlled process was investigated at 70 C, with ethyl 2-bromoisobutyrate as an initiator and 4,4 0 -dinonyl-2,2 0 -bipyridyne (dNbpy)/CuBr as a catalyst system in anisole. The monomer reactivity ratios (r values) were obtained by the application of the conventional linearization Fineman-Ross method (r GMA ¼ 1.24 6 0.02 and r MMA ¼ 0.85 6 0.03) and by the Mayo-Lewis method (r GMA ¼ 1.19 6 0.04 and r MMA ¼ 0.86 6 0.03). The molecular weights and polydispersities of the copolymers exhibited a linear increase with GMA content. The copolymer compositions were determined by 1 H-NMR and showed a domination of syndiotactic structures. The glass-transition temperatures (T g ) of the copolymers analyzed by differential scanning calorimetry (DSC) decreased in the range 105-65 C with increasing GMA units.

“…11,21,25,26 On the other hand, acrylic-based coatings deposited by wet deposition techniques are commonly applied on Al and other solid substrates for corrosion protection purposes. 28 Glycidyl methacrylate (GMA)-based copolymers successfully entered the eld of epoxy resin technologies due to the ease of copolymerization with other matrices 29,30 and the possibility to prepare homogenous or heterogeneous polymer networks with tailored properties. 27 Epoxies can be distinguished among very reactive chemical moieties due to the high reactivity of the oxirane ring leading to both crosslinking and further functionalization reactions via ring opening.…”

In the context of a universal search for alternatives to chromate-based coatings, which are toxic for both human beings and the environment, a multilayer coating for Al protection purposes is developed and investigated in the current work. The first layer is selected to be a hexamethyldisiloxane-based plasma polymer film (PPF), deposited by Plasma Enhanced Chemical Vapor Deposition (PECVD), due to a number of interesting features that are characteristic of plasma polymers. The second layer is synthesized via the polymerization of the 2-ethylhexyl acrylate monomer initiated from the free radicals trapped on the surface of the PPF during its growth. A subsequent layer of a copolymer of 2-ethylhexyl acrylate and glycidyl methacrylate, poly(EHA-co-GMA), is deposited by spin coating to increase the corrosion resistance of the coating. An improvement in the anti-corrosion properties of the multilayer coating by approximately three orders of magnitude as compared to the uncoated Al substrate is observed. Further enhancement of the adhesion and scratch resistance properties is addressed via UVcrosslinking and the incorporation of in situ generated silica nanoparticles into the final layer.
