The paper deals with the synthesis and characterization of seven polypyromellitimide samples having varying contents of phosphine oxide and ether linkages in the backbone with pendant maleimido groups. Curing characteristics and thermal stability of polymers were evaluated by differential scanning c
## Abstract The synthesis of some heterocyclicβaromatic sulphones with potential acaricidal properties is described. The benzene nucleus in these sulphones is substituted either with a __para__βchlorine atom or with three chlorine atoms in positions 2, 4 and 5. The heterocyclic nuclei used are pyri
