Properties of irregular poly-(arylate-arylene sulphonoxides) based on oligoarylene sulphonoxides with various degrees of polymerization

Investigation of the Regularities of the Synthesis of Unsaturated Polyesters by the Method of Acceptor-Catalytic Polycondensation

“…The main parameters that determine the properties of polymers obtained under conditions of acceptor-catalytic polycondensation are the nature of the starting reagents and solvent, the temperature and duration of the reactions, and the concentration of the starting substances. The role of the tertiary amine in carrying out: acceptor-catalytic polycondensation is well known [9][10][11][12][13][14][15][16][17][18]. Therefore, it seemed expedient to find the optimal ratio of bisphenol: triethylamine in the synthesis of unsaturated halogen-containing block copolysulfonarylate.…”

The Effect of Various Oligoether Additives on the Formation of the Physicomechanical Properties of Polysulfone

“…By numerous researches it is shown that the polymers containing dichlorethylenic >С=ССl2, have good fire proofness in combination with high mechanical and thermal characteristics [11][12][13][14][15][16][17][18][19]. All this was the basis for carrying out the researches on creation and investigating the main properties of new composite materials on the basis of polysulfone on the basis of 4.4 '-dihydroxi-2.2-difenilpropana and oligoefir with dichlorethylenic >С=ССl2 -groups.…”

High Performance Aromatic Polyethersulfones

“…Numerous studies have shown that polymers containing dichloroethylene groups, in addition to fire resistance, have high mechanical and thermal properties [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].…”
