Polyester resins having improved rheological properties

Flame retardant compositions comprising a polyester resin having a melt strength higher than 8 centinewton an intrinsic viscosity greater than 0.8 dl/g, suitable for the preparation of foamed cellular material and a flame retardant compound capable of not reducing below 3 Nm the torque intake of the resin in a heating test at 280&deg; C. under nitrogen for 10 minutes in the presence of 10% by weight of the flame retardant compound.

Foamed polyester resins with flame retardant properties

A process for the preparation of aromatic polyester resins, in which the resin obtained from the polycondensation phase in the molten state conducted by utilizing a titanium based compound as a catalyst, is subjected to a solid state polycondensation reaction in the presence of a dianhydride of a tetracarboxylic acid.
