Abstract

Masterbatch comprising a dimeric and/or trimeric cyclic ketone peroxide dispersed in a polymeric matrix with a porosity, expressed as percentage of voids on the volume of the matrix, of 0.1-80 vol %, wherein said masterbatch comprises, per 100 g of polymeric matrix, 1-30 g dimeric and/or trimeric cyclic ketone peroxide and less than 0.20 g saturated hydrocarbons with 17-51 carbon atoms.

First claim

The invention claimed is:

1. A masterbatch comprising 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane dispersed in a polymeric matrix with a porosity, expressed as percentage of voids on the volume of the matrix, of 0.1-80 vol %, wherein said masterbatch comprises, per 100 g of polymeric matrix, 1-30 g 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane and less than 0.20 g saturated hydrocarbons with 17-51 carbon atoms.

2. The masterbatch according to claim 1 , comprising, per 100 g of a polymeric matrix, less than 0.15 g saturated hydrocarbons with 17-51 carbon atoms.

3. The masterbatch according to claim 2 , comprising, per 100 g of a polymeric matrix, less than 0.10 g saturated hydrocarbons with 17-51 carbon atoms.

4. The masterbatch according to claim 1 , wherein the resulting masterbatch comprises 4-18 g of 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane per 100 g of polymeric matrix.

5. The masterbatch according to claim 1 , wherein the polymeric matrix has a porosity of 10-60 vol %.

6. The masterbatch according to claim 1 , wherein the polymeric matrix consists for at least 50 wt % of polypropylene, polyethylene, ethylene vinyl acetate polymer or any mixtures thereof.

7. The masterbatch according to claim 6 , wherein the polymer is a polymerization reactor grade or extruded porous grade.

8. A process for the preparation of a masterbatch according to claim 1 , comprising
(i) providing a polymeric matrix with a porosity, expressed as percentage of voids on the volume of the matrix, of 0.1-80 vol % and
(ii) impregnating said polymeric matrix with a formulation comprising 3,6,9-triethyl-3,6,9-trimethyl-1,4,7-triperoxonane and one or more solvents.

9. A method for the modification of a polymer, comprising adding the masterbatch according to claim 1 to a polymer.

10. The method according to claim 9 , wherein the modification involves cracking of polypropylene homopolymers and/or copolymers of propylene and ethylene.

11. The method according to claim 9 , wherein the modification involves the introduction of long chain branches or crosslinking of polyethylenes.
