Abstract: In one aspect, methods of depolymerization are described herein comprising providing a synthetic polymer including a hydroxylated aliphatic backbone or hydroxylated backbone segments, and homolytically activing O—H bonds of the hydroxyl groups. Homolytic activation induces the formation of alkoxy radical intermediates followed by C—C bond β-scission events breaking the polymer backbone into depolymerization products. In some embodiments, depolymerization products comprise alkyl radical intermediates reduced by hydrogen atom transfer. Moreover, in some embodiments, the depolymerization products are further reacted into difunctionalized products or comprise functionalities derived from the polymer structure. The difunctionalized products can subsequently be employed in polymerization processes for the production of additional synthetic polymers.

Abstract: The present invention is directed to a process for preparing amides or polyamides by replacing isocyanate starting materials of a catalyzed thermal reaction with aromatic carbamates. Through the catalyzed thermal process involving a non-isocyanate precursor of the present invention, efficiency for producing amides or polyamides can be significantly improved, and the impure side products produced from a side reaction of isocyanate can be greatly curtailed. Hence, amides or polyamides of high purity and yield can be achieved. The invention also relates to a process for preparing aromatic carbamates, the new non-isocyanate precursors for amides or polyamides.

Abstract: A method of forming lightweight structures from particle networks includes functionalizing edges of particles of an anisotropic material, exfoliating of the particles to form sheets of the material, aligning the sheets of material to form a network of multi-layered and aligned particles, and forming a structure out of the network of particles. One example uses graphite powder mixed into 4-aminobenzoic acid for edge functionalization, and exfoliation occurs with sonication in a solvent. The resulting particles undergo alignment with an aligning nozzle that also dispenses the aligned particles to form a structure.

Abstract: The invention relates to a flame-resistant polyamide as a product of the condensation of dicarboxylic acids with diamines and with a flame-retardant phosphorus compound, which flame-resistant polyamide is characterized in that the flame-resistant polyamide FR contains, in the main chain thereof phosphinic acid amide structural units of formula (II) —PO(R1)—NH— (II) in addition to the amide structural units of formula (I) CO—NH— (I), in which formula (II) RI means hydrogen or an organic group and can differ in the individual phosphinic acid amide structural units within the main chain and that the polyamide FR achieves a relative viscosity, measured as a 1% solution in 96% sulfuric acid at 25° C., of at least 2.0 (in accordance with DIN 51562). The invention further relates to a method for producing said flame-resistant polyamide FR. In said method, one or more diamines are polycondensed with one or more dicarboxylic acids under pressure and at elevated temperature in the presence of water and with one or more diphosphinic acids and/or one or more phosphino-carboxylic acids by means of a polyamide synthesis. After the polycondensation, the pressure in the reaction chamber is reduced to less than 1 bar. The flame-resistant polyamide can be advantageously used to produce molded bodies, in particular films, components, and filaments or filament yarns.
