“…The present literature already contains a number of valuable reviews [12,13,[18][19][20][21][22] and books [23][24][25] on block copolymer systems. This review aims to compliment them by providing an introduction to block copolymer theory in the context of the simple diblock copolymer melt.…”

As a result of important advances over the last decade, block copolymer melts have become an excellent model system for studying fundamental phenomena associated with molecular self-assembly. During this time, good quantitative agreement has been achieved between theory and experiment in regards to equilibrium phase behaviour, and with it has emerged a thorough understanding in terms of simple intuitive explanations. The theoretical contributions to this effort are largely attributed to mean-field calculations on a standard Gaussian model. Here, we review this present understanding of block copolymer phase behaviour, the model and its underlying assumptions, the mean-field approximation and its limitations, and the attempts to incorporate fluctuation corrections. Rather than following the traditional rigorous derivations, we present slightly more intuitive and transparent ones in such a way to stress the close connection between the related calculations. In this way, we hope to provide a valuable introduction to block copolymer theory.

“…These difunctional polymers or oligomers can be used for preparing novel block copolymers (diblock, triblock, and so on) and interesting materials such as amphiphilic oligomers and supramolecules . For these purposes, poly(alkylene glycol)s and terminal-functionalized oligomers from condensation polymers, e.g., polyamides or polyesters, may be used …”

Functionalization and Applications of Telechelic Oligopropylenes: Preparation of α,ω-Dihydroxy- and Diaminooligopropylenes

et al. 2005

Difunctional propylene oligomers which may be used for preparing novel block copolymers were synthesized from telechelic oligomers containing two terminal vinylidene double bonds (PP-TVDs). The PP-TVDs were converted to α,ω-dihydroxyoligopropylenes (PP-OHs) in good yield by hydroboration with BH3·THF or 9-BBN, followed by oxidation. Multiple NMR signals from the α-methylene protons and the β-methyl carbons were ascribed to epimers formed during the hydroboration. α,ω-Diaminooligopropylene (PP-NH2) was prepared from PP-OH via tosylate and azide. Copolymerizations of PP-NH2 with terephthalic acid were carried out, and copolymers with molecular weights larger than that of the parent polymer were obtained.

“…For example, the prefix “oxo” denotes the characteristic group “=O” [26–27] and, consequently, “oxocarbenium ion” is a carbenium ion with the group “=O” (i.e., a synonym of an acylium cation, 5 ; Fig. 2), which is the other use found in the literature for this term [23,28]. Not only is the term “oxocarbenium ion” not suitable for describing intermediate 1 , but also it is used to name another intermediate more accurately.…”

The nomenclature of cations R1C(=O+R3)R2 (R1, R2, R3 = H or organyl) has been examined and shown to be in a state of immeasurable confusion: a pragmatic recommendation is made that the generic term “carbonylonium ions” should be adopted for these intermediates, which comprises the terms “aldehydium” (R1 = H, R2, R3 = H or organyl) and “ketonium ions” (R1, R2 = organyl, R3 = H or organyl) for the corresponding aldehyde- and ketone-based intermediates, respectively.
