Definitions
- the invention relates to a treatment of a thermoplastic polymer comprising in copolymerized form or in grafted form a monomer with an epoxide function and comprising said monomer with an epoxy function in free form also called residual monomer, that is to say n ' which have not reacted by copolymerization or by grafting.
- the treatment is intended to capture said residual monomer.
- the invention also relates to the compositions and blends comprising such thermoplastic polymers obtained by said treatment.
- Degassing can, for example, be carried out in degassing silos supplied with nitrogen or hot air. Removal of residual compounds can also be carried out in the molten state in devices called devolatilizers, as is the case in the manufacture of polystyrene. In this case, the molten polymer is dispersed in an enclosure maintained under high vacuum, the volatiles being thus entrained under the effect of the vacuum. Devolatilization can also be carried out in an extruder provided with one or more degassing wells.

- the MFI will preferably be between 5 and 20 g / 10 min at 190 ° C. under 2.16 kg.
- the advantage of the pure or included trapping additive in a masterbatch is that it can be introduced directly into the molten polymer by means of a compounding operation in an extruder. It can be injected at any time, either before or during the extrusion of the polymer. The result is a real ease of implementation.
- the time necessary for the trapping additive to interact is between substantially 1 s to 10 min at a temperature between substantially 0 ° C and 250 ° C.
- the trapping additive, pure or included in a masterbatch is added in an amount sufficient to reduce the amount of free monomer in the polymer.

- the method for assaying the residual compounds used is as follows. In a sealed bottle, 2 g of polymer sample are weighed which is dissolved in cold tetrahydrofuran, then the solution obtained is heated for 10 minutes at 50 ° C. The polymer is then precipitated using a methanol solution containing nonane as an internal standard. The supernatant liquid is then injected into the chromatograph.
- CPG gas chromatography
- LOTADER® AX8900 terpolymer comprising ethylene / methyl acrylate / glycidyl methacrylate (GMA)
- GMA ethylene / methyl acrylate / glycidyl methacrylate
- LOTADER® AX8900 that we used include between 50 and 1000 ppm by weight of free GMA.
- a basket containing LOTADER® AX8900 granules is placed in a glass tube swept by a stream of nitrogen (20 ml / min).
- the glass tube is heated for several hours (0, 4 and 8 hours) at 50 ° C and the gas stream is trapped in water.
- the residual GMA content of the LOTADER® AX8900 in the nacelle is then determined by CPG according to the method described above. The results are reported in Table 1.
- the so-called residual or free GMA in the copolymer corresponds to the monomeric GMA which has not copolymerized and which remains included in the mass of copolymer at room temperature.
- Table 1 at constant temperature (50 ° C), the percentage of GMA released increases with time. After 8 hours, approximately half of the residual GMA is released.
- the copolymer can still contain free GMA in a non-negligible amount. It is therefore difficult to relate an odor level to a content of this or that residual compound.
- the LOTADER® AX8900 copolymer (composition described above) is extruded according to the following extrusion conditions.
- the extruder is defined in five zones ranging from zone 1 to zone 5. Zone 5 is the closest to the extruder die while zone 1 is the zone furthest from the die.
- comparison 4 The same extruder and the same extrusion conditions as those described in comparison 3 are used.
- the difference between comparison 4 and comparison 3 lies in the coextrusion of the LOTADER® AX8900 copolymer and 2.4% by weight of a LUCALEN® A 31 10 M acid copolymer (ethylene / butyl acrylate / acrylic acid copolymer) sold. by ELENAC.
- the copolymer entering zone 1 of the extruder has an initial content of residual GMA of 177 ppm and a content of residual GMA at the outlet of the die of 171 ppm.
- the drop in the GMA content is therefore not significant, since the acid function linked to the copolymer is perhaps not sufficiently free as can be that of an organic acid.
- Example 5 illustrates the invention.
- the same extruder and the same extrusion conditions as those described in comparison 3 are used.
- the copolymer entering zone 1 of the extruder has an initial content of residual GMA of 177 ppm and an initial content of methyl acrylate of 80 ppm .
- the residual GMA content at the outlet of the die is not detectable because it is too small (between about 0 and 5 ppm).
- the residual methyl acrylate content at the outlet of the die is 75 ppm.
- Copolymerized GMA is not affected by the treatment. Indeed, its content of copolymerized GMA is approximately 8% before extrusion and also approximately 8% after extrusion.
- Example 6 illustrates the invention.
- the same extruder and the same extrusion conditions as those described in comparison 3 are used.
- the residual GMA content at the outlet of the die is not detectable because it is too small (between about 0 and 5 ppm).
- the residual methyl acrylate content at the outlet of the die is 80 ppm.
- the addition of the acidic zeolite can have such a remarkable effect on the content of free GMA, without influencing the content of copolymerized GMA; • the acid zeolite has an effect on the content of free GMA but little or no effect on the content of free methyl acrylate.
- Example 7 illustrates the invention. The same extruder and the same extrusion conditions as those described in comparison 3 are used. The difference between Example 7 and Comparative 3 resides in the injection into the extruder, during the extrusion of the LOTADER® AX8900 copolymer, of 0.1% by weight of stearic acid, the LOTADER®AX8900 copolymer and 1 stearic acid thus being coextruded.
- the copolymer entering zone 1 of the extruder has an initial content of residual GMA of 177 ppm and a content of residual GMA at the outlet of the die of 148 ppm.
- Example 5 The same test is carried out as in Example 5, but with 1% of a hydrophilic zeolite, SYLOSIV 4A, instead of a hydrophobic ZSM zeolite.
- SYLOSIV 4A zeolite is marketed by W.R. Grace & Co, micronized and highly porous, with an average pore diameter of 4 angstroms.
- the pH of this 5% zeolite in water measured according to the method of DIN EN ISO 787-9 is 11.5.
- the LOTADER® AX8900 copolymer and the zeolite are coextruded.
- Example 5 The same test is carried out as in Example 5, but with Lacqrène® 1450N polystyrene as the polymer.
- the assay method for styrene monomer is identical to that used for the assay of GMA. It is found, after analysis by GC, that the polymer entering zone 1 of the extruder has an initial free styrene content of 250 ppm and a free styrene content at the outlet of the die of 250 ppm. The zeolite therefore had no effect on the elimination of the residual styrene.
- This example shows that a zeolite can be effective for a residual compound (GMA) but not necessarily for another (styrene). The trapping function cannot therefore be transposed from one resin to another and therefore from one residual compound to another.
- Table 2 summarizes the% of residual or free monomer remaining in the polymer after treatment of the polymer.
- the proportion of residual or free GMA released depends mainly on the reaction temperature, the reaction time, the pressure, the quantity of free GMA to be trapped and of the amount of trapping additive introduced into the copolymer. Regarding this last point, the more trapping additive is added, the more the free GMA will be trapped in the copolymer until it reaches a plateau where it will no longer be useful to add trapping additive because all the Free GMA will have been trapped.
