## Abstract Two new homologous series of semiflexible main‐chain polyesters on the basis of 4‐hydroxy‐and 4‐carboxycinnamic acid in conjugation with 2‐__tert__‐butylhydroquinone and alkylene spacers with 3 to 8 methylene groups were prepared by low‐temperature solution condensation. The thermotropi

The dilatometric properties and Roga index of two orthocoking coals, subject to extraction with n-pentane, methylene chloride and chloroform, were determined in order to investigate the influence of low-molecular weight substances on coking properties of the coals. With increasing extraction yield,
The hydrogenolysis reaction of coal using red-mud and sulphur as catalyst has been carried out at 400 and 45O"C, 10 MPa or 3 MPa of hydrogen, and 3 MPa of hydrogen plus 7 MPa of nitrogen. The mean chemical structures of the asphaltenes and oils produced show that at first the portion with relatively
