“…As an example, ABA triblock copolymers consisting of a polysulfone central block joined to two blocks of PEO were synthesized wileyonlinelibrary.com/journal/pi by condensation reaction of halide end-functionalized telechelic polysulfone with trimethylsiloxy functionalized monotelechelic poly(phenylene oxide). 154 The same approach was also applied for the synthesis of multiblock copolymers containing polysulfone with PEO 155 polydimethylsiloxane 156 -160 blocks. Alternatively, the reverse approach using hydroxyl-terminated polysulfone with diethylamine-terminated polydimethylsiloxane, 156,157,161 -163 dibromo-terminated poly(vinylidene fluoride) 164 or polysilane blocks 165 can also be utilized.…”

A new fluorinated poly(aryl ether) with reactive benzocyclobutene groups as the side chain was successfully synthesized. This polymer showed a number-average molecular weight (Mn) of 200,000 and had good solubility and film-forming ability. After being postpolymerized at high temperature (>200 °C), the polymer film converted to a cross-linked network structure, which was insoluble in the common organic solvents. Such results suggest that the postpolymerization is an efficient way to achive the balance between the solubility and the solvent resistance of the polymer. TGA data showed that the postpolymerized polymer had a 5 wt % loss temperature at 495 °C and a residual of 61% at 1000 °C under N2. The cross-linked film also exhibited good dielectric properties with an average dielectric constant of about 2.62 in a range of frequencies from 1 to 30 MHz. With regard to the mechanical properties, the cross-linked film had hardness, Young's modulus, and bonding strength to a silicon wafer of 1.22, 8.8, and 0.89 GPa, respectively. These data imply that this new polymer may have potential applications in the electrical and microelectronics industry.

“…Another method for the formation of block copolymers is the reaction of two reactive polymer chain-ends to form a covalent bond between two homopolymers. [8,9] However, quantitative yields of these post polymerization reactions are normally not obtained limiting the use of this strategy. A potential solution to overcome these difficulties is the implementation of telechelic or end-group functionalized polymers that are capable of undergoing selfassembly to form complex architectures.…”

A novel methodology for the formation of block copolymers has been developed that combines ring-opening metathesis polymerization (ROMP) with functional chain-transfer agents (CTAs) and self-assembly. Telechelic homopolymers of cyclooctene derivatives end-functionalized with hydrogen-bonding or metal-coordination sites are formed through the combination of ROMP with a corresponding functional CTA. These telechelic homopolymers are fashioned with a high control over molecular weight and without the need for post-polymerization procedures. The homopolymers undergo fast and efficient self-assembly with their complement homopolymer or small molecule analogue to form block-copolymer architectures. The block copolymers show equivalent association constants as their small molecule analogues described in the literature, regardless of size or nature of the complementary unit or the polymer side chain.
