Definitions

  • compositions according to the invention are further characterized in that the point of inflection corresponding to the exponential increase in the elongational viscosity as a function of time is generally less than 3 seconds, preferably less than 2 seconds.
  • thermoplastic aliphatic polyesters is intended to denote, for the purposes of the present invention, aliphatic polyesters and copolyesters in which the ester functions are separated by a chain of at least 2 carbon atoms, optionally substituted.
  • compositions according to the invention usually have a crystallization temperature, measured by differential thermal analysis, on the first cooling pass, after having erased the thermal history of these and with a scanning speed of 10 ° Kymin, at minus 1 ° C higher than that of the corresponding compositions characterized by an RMFI value of between 0.85 and 1.05.
  • the reaction zone has the function of ensuring the reaction.
  • the radical generator When the radical generator is introduced into the extruder through a thermoplastic aliphatic polyester, in particular a polymer of ⁇ - caprolactone, it is preferably introduced into the feed zone of the extruder.
  • a first extruder used is the WERNER & PFLEIDERER ZSK® 40 co-rotating twin screw extruder.
  • the diameter of the screws is 40 mm and their length is 1360 mm.
  • the screw rotation speed is 200 rpm (rotations per minute).
  • the pumps 1 and 1 ' are pumps of the GILSON 305 or 306 type.
  • the pump head 1' provided for carbon dioxide is equipped with a thermostat kit 5/10 / 25SG from GILSON which allows the head to be cooled to -10 ° C.
  • the coolant is isopropanol cooled in a JUBALO F30 cryo-thermostat.
  • the measurement result (RME diagram) is expressed by the variation, at 80 ° C, of the elongational viscosity in the molten state (expressed in kPa.s) as a function of time (expressed in s) for an elongation gradient (expressed in s ⁇ l) of l. Movies
  • Impact resistance is measured according to ISO standard 7765-1 (1998) (method A). The weight thus determined is related to the thickness of the sample to express the result in g / ⁇ m.
  • Two films (No. 1.1, 1.2) were produced starting from the composition according to Example 1 in the manner described above and with the conditions listed below.
  • Example 1 was reproduced by replacing the poly- ⁇ -caprolactone CAPA®680 with a mixture of 40% by weight of the poly- ⁇ -caprolactone CAPA®680 and 60% by weight of the poly- ⁇ -caprolactone CAPA ®650.
  • the number average molecular mass, measured by gel permeation chromatography, is 55,000 g / mole.
  • Example 3 was repeated in the absence of DHBP.
  • a film (No. 5.1) was made from the composition according to the example
