“…303,304 Several examples of PEGMA-based amphiphilic copolymers have also appeared in recent literature. [307][308][309][310][311][312][313]317 These kinds of polymers have received great interest in the past few years. 318 They can be considered analogous to PEG-based copolymers, resembling them from a chemical point of view, but with the advantage of being polymerizable via mild controlled radical methods.…”

“…[36][37][38] Previously we demonstrated that hybrid amphiphilic block copolymers comprising a hydrophilic glycosylated polypeptide block and a hydrophobic polystyrene block could efficiently stabilise styrene latex formation. 40 Phenyl-L-alanine (PA) was chosen as the amino acid for this block due to the structural resemblance of the phenyl substituent with styrene. For the purpose of utilizing polypeptide block copolymers as macromolecular stabilisers in this process, it was necessary to carefully select the hydrophobic polypeptide block.…”

Diblock copolymers consisting of poly(L-phenyl alanine) and poly(benzyl-L-glutamate) or poly(CBZ-L-lysine), respectively, were synthesized via sequential NCA polymerization. After deprotection, subsequent partial glycosylation of the glutamic acid and lysine units with galactosamine hydrochloride or lactobionic acid yielded amphiphilic block copolypeptides. Moreover, a triblock copolymer poly(L-phenyl alanineb-L-benzyl glutamate-b-propargylglycine) was obtained and glycosylated by 'click' chemistry. Glycosylated block copolypeptides showed improved water solubility and circular dichroism (CD) confirmed the pH dependence of the helix-coil transition. The block copolypeptides were found to be efficient stabilizers in the emulsion polymerization of styrene offering a facile method for the synthesis of polystyrene nanoparticles in the range of 100-140 nm depending on the block copolymer composition and emulsion concentration. This establishes an example of functional polymer additives fully based on renewable building blocks in nanomaterial synthesis.This journal is

“…[12] The performance of the composite latex particles is directly affected by their morphology and due to its practical importance, particle morphology has received a considerable attention in the literature. [13][14][15][16][17][18][19][20][21][22][23][24][25][26] Several authors reported theoretical approaches aimed at predicting the particle morphology, but most of the methods are based on two limiting assumptions: either the polymer chains do not move from the point that they are formed [25,[27][28][29][30][31] or the equilibrium morphology is attained instantaneously. [11,[32][33][34][35][36][37][38][39][40] There are only few works in the literature that take into account all relevant kinetic and thermodynamic effects.…”

Asua, A new approach for mathematical modelling of the dynamic development of particle morphology, Chemical Engineering Journal (2016), doi: http://dx. AbstractA new model for the dynamic evolution of the morphology of polymer-polymer latex particles has been developed. This model overcomes the limitations of the existing methodologies that were only able to provide the morphology of a single particle, which is only a restricted view of the real system that contains a distribution of particle morphologies. Taking into account the relevant kinetic and thermodynamic effects, the new model calculates the distribution of morphologies for the whole population of polymer particles with less computational effort than that needed by the previous models to calculate the morphology of a single particle. The model was validated by fitting the evolution of particle morphology of composite particles during polymerization of methyl methacrylate on a polystyrene seed. Furthermore, the ability of the model to predict the evolution of the particle morphology for different cases was explored.
