FERROMAGNETIC POLYMER DISPERSIONS BASED ON METHACRYLIC ESTERS. THE INFLUENCE OF COMPOSITION SOLUBILITY PARAMETER ON THE REGULARITIES OF OBTAINING

The influence of the solubility parameter on the regularities of obtaining polymer dispersions based on copolymers of 2-hydroxyethyl methacrylate and glycidyl methacrylate are investigated. A method of nucleating polymerization for obtaining micron-sized monodispersed spherical materials is proposed. The influence of the nature and amount of solvent on the dispersion characteristics of the polymer particles has been established.

Theory and practice of obtaining composite materials based on polymer blends

The regularities of the thermodynamic compatibility of various industrially produced polyolefins and heterochain polymers and the possibility of obtaining composite materials based on their mixtures with significantly increased performance properties based on existing production facilities and process equipment have been identified.

Ефект параметра розчинності у суспензійній полімеризації композицій метакрилових естерів з полівінілпіролідоном

The effect of the solubility parameter on the regularities of the hydrogel suspension obtaining based on the copolymers of 2-hydroxyethyl methacrylate and glіcidil metakrilat with polyvinylpirrolydone is investigated. The influence of the solvent nature on the diffusion processes in the suspension polymerization, the dispersion characteristics of hydrogel particles and kinetics of polymerization is determined.

Looking for a Model Solvent to Disperse Asphaltenes

Petroleum could be seen as a system of asphaltenes dispersed in other petroleum components. The petroleum components excluding the asphaltenes are referred to in this paper as Petroleum Medium that Disperses the Asphaltenes – PMDA). This paper proposes a methodology to determine solubility parameter of the PMDA by identifying a model solvent which, when added to the petroleum, does not affect the asphaltenes phase behavior.
