Abstract

The disclosure relates to a method and a system for feeding a liquid organic peroxide to a polymer melt processing equipment. The feeding method comprises transporting at least one liquid organic peroxide ( 13 ) in undissolved admixture with an inert liquid cooling carrier ( 4 ) from a controlled-temperature section ( 3 ) to a polymer melt processing equipment.

Claims (14)

1 . A method for feeding a liquid organic peroxide to a polymer melt processing equipment, the method comprising:

storing at least one liquid organic peroxide in a storage arranged in a controlled-temperature section;

mixing the at least one liquid organic peroxide and an inert cooling carrier in a mixing section arranged in the controlled-temperature section, wherein mixing is performed without dissolving the at least one liquid organic peroxide in the inert cooling carrier; and

transporting the at least one liquid organic peroxide in undissolved admixture with the inert cooling carrier from the controlled-temperature section to a polymer melt processing equipment arranged outside the controlled-temperature section,

wherein the inert cooling carrier comprises an aqueous liquid is volatile under melt processing conditions.

2 . The method of claim 1 , wherein the inert cooling carrier consists of demineralized water.

3 . The method of claim 1 , wherein the polymer melt processing equipment comprises an extruder.

4 . The method of claim 1 , wherein mixing is mechanical mixing.

5 . The method of claim 1 , wherein the method further comprises feeding the inert cooling carrier to the mixing section at a predetermined flow rate.

6 . The method of claim 1 , wherein the method further comprises pumping the least one liquid organic peroxide from the storage to the mixing section at a predetermined flow rate.

7 . The method of claim 1 , wherein the polymer is a polyolefin.

8 . A method for melt processing a molten polymer comprising the method for feeding at least one liquid organic peroxide to a polymer melt processing equipment as defined in claim 1 , wherein the method for melt processing the molten polymer further comprises melt processing the molten polymer in the presence of the at least one organic peroxide and the inert cooling carrier in the polymer melt processing equipment, and removing the inert cooling carrier from the molten polymer.

9 . The method of claim 8 , wherein melt processing comprises extruding.

10 . The method of claim 8 , wherein removing is performed by venting the polymer melt processing equipment.
