“…Acrylates and methacrylates are preferred monomers for binder resins for automotive coatings, providing superior chemical and mechanical properties as well as excellent photostability and resistance to hydrolysis [2][3][4][5][6]. In addition, the ability to equip the polymer backbone with functional groups (hydroxyl, epoxy, amide, carboxylic acid, etc.)…”

A comprehensive stochastic simulator that considers all probable secondary reactions essential for the description of high-temperature radical copolymerization of acrylate/methacrylate is implemented based on previously established accelerating techniques. The comparisons between the predictions and six experimental datasets are detailed for semi-batch copolymerization of 2-hydroxyethyl acrylate (HEA) with n-butyl methacrylate (BMA) under starved-feed condition. Macroscopic properties -free monomer and molar mass (MW) average profiles, final polymer molecular mass distributions, and the variation of acrylate composition with time-are reasonably well predicted over the range of initiator and comonomer levels studied. The simulation output also predicts the weight fraction and MW averages of the polymer chains that contain no HEA functionality, results that are compared to the experimental extractables obtained after crosslinking the copolymer resin. The general trends are well-captured, indicating that the model can be utilized in the future to optimize recipe and operating conditions to minimize the production of the non-functional material.

“…Alloys of poly(butylene terephthalate) (PBT) and PPE are of particular interest. Features of PBT include chemical resistance and good processability, however, the Tg around 34 °C results in dimensional changes at relatively low temperatures [ 30 , 31 ]. PPE has a Tg above 200 °C, good dimensional stability and properties at elevated temperatures, but is more difficult to process [ 30 , 31 ].…”

Polyphenylene ether (PPE) telechelic macromonomers are unique hydrophobic polyols which have been used to prepare amphiphilic block copolymers. Various polymer compositions have been synthesized with hydrophilic blocks. Their macromolecular nature affords a range of structures including random, alternating, and di-and triblock copolymers. New macromolecular architectures can offer tailored property profiles for optimum performance. Besides reducing moisture uptake and making the polymer surface more hydrophobic, the PPE hydrophobic segment has good compatibility with polystyrene (polystyrene-philic). In general, the PPE contributes to the toughness, strength, and thermal performance. Hydrophilic segments go beyond their affinity for water. Improvements in the interfacial adhesion between polymers and polar substrates via hydrogen bonding and good compatibility with polyesters (polyester-philic) have been exhibited. The heterogeneity of domains in these PPE based block copolymer offers important contributions to diverse applications.

“…Such industries include the aeronautics industry, microelectronics, or fireproof overalls. Examples of such materials are polyimide (Kapton®) [3][4][5], polyetheretherketone (PEEK) [6], or aromatic polyamides such as Nomex® (or Conex®) or Kevlar® (or Twaron®) [7,8]. These materials all exhibit extreme fire resistance and thermal stability [9][10][11][12][13].…”

This article reports the thermal and fire behaviors of a high performance polymer, namely polyimide (PI). These behaviors were investigated using different techniques and tests, i.e., pyrolysis-Gas-Chromatography/Mass-Spectrometry (py-GC/MS) and TGA coupled with a Fourier Transform InfraRed spectrometer (TGA-FTIR), and mass loss cone (MLC) at different heat fluxes. It was observed that the thermal stability of PI strongly depends on the oxygen concentration. The main identified gases released during thermal degradation are: carbon dioxide, carbon monoxide, water and organic compounds (phenol, aniline, cyanobenzene, dicyanobenzene, 4-aminophenol, benzene, 2-(4-hydroxyphenyl)isoindoline-1,3-dione, phthalimide, dibenzofuran, and diphenylether). The ignition of PI in MLC experiment is observed under an external heat flux of 60 kW/m 2. In that case, the peak of heat released by polyimide is only 30 kW/m 2. Based on these investigations, a possible decomposition pathway of PI is proposed.
