First ESR studies are reported on oriented carbynoid samples prepared by chemical dehydrofluorination of poly(vinylidene fluoride) films. Two types of paramagnetic centres (PC), denoted as C-M1 and C-M2, and an anisotropic broad line were detected. The spectra of the PC C-M1 are isotropic with a g-value of . The absorption by given PC is well saturated at room temperature and the PC C-M1 can be attributed either to free radical states or pinned quasi-particles similar to topological Su-Schrieffer-Heeger solitons. The ESR and microwave photoconductivity results obtained confirm the quasi-1D nature of the carbon chains, being the structural elements of the samples studied, and agree with the assumption that the ground state of carbon chains is a state with a spin density wave (SDW) realized at room temperature. The ESR spectrum of the PC C-M2 consisting of a series of unsaturated lines is anisotropic both in relation to the static magnetic field and in relation to the magnetic component of the microwave field. The study of the interaction dynamics of the microwave field with PC C-M2, the absorption dependence with increase of the microwave field and the temperature dependence allow us to attribute the PC C-M2 to mobile quasi-particles, being domain walls in the alternated spin density distribution, tentatively solitons in the SDW. It has been found that spin waves associated with the PC C-M2 can be observed in samples treated thermally at for 2 hours (the samples contained fluorine with atomic ratio F/C = 3/7 and oxygen at 20 at.%). It has been proven that the spin waves' excitation and the formation of quasi-particles like solitons can represent the same process.

m-Xylylene bismaleimide, Compimide † MXBI (hereafter MXBI), was developed as a building block for formulating bismaleimide resins with improved processability. MXBI on its own, or in combination with 4,4′bismaleimidodiphenylmethane (Compimide MDAB, hereafter MDAB) and with 2,2′-diallylbisphenol-A as a comonomer, provides very low-melting resin blends, which can be processed at temperatures around 60-80°C via RTM (Resin Transfer Moulding), VARIM (Vacuum Assisted Resin Infusion Moulding), prepregging, and wet filament winding (FW). Uncured and cured resin properties were evaluated. The mechanical property spectrum of the MXBI/MDAB/diallylbisphenol-A system with varying MXBI/MDAB ratio shows almost equivalent contributions of MXBI and MDAB to the mechanical properties of a system. Higher MXBI proportions are responsible for lower resin viscosities and hence superior processability.
