Abstract
A method for producing a polymer composition comprises the steps of providing a compatibilizing agent, providing a heterophasic polymer composition, providing a second polymer composition comprising recycled polymer; mixing the compatibilizing agent, the heterophasic polymer composition, and the second polymer composition, and generating free radicals in the heterophasic polymer composition and the second polymer composition. At least a portion of the compatibilizing agent is believed to react with the free radicals generated in the heterophasic polymer composition and the second polymer composition.
Claims15
A method for producing a polymer composition, the method comprising the steps of:
- (a) providing a compatibilizing agent, the compatibilizing agent comprising two or more functional groups capable of reacting with a free radical in a radical addition reaction;
- (b) providing a heterophasic polymer composition, the heterophasic polymer composition comprising a propylene polymer phase and an ethylene polymer phase;
- (c) providing a second polymer composition, the second polymer composition comprising recycled polymer;
- (d) mixing the compatibilizing agent, the heterophasic polymer composition, and the second polymer composition;
- and
- (e) generating free radicals in the propylene polymer phase and the ethylene polymer phase of the heterophasic polymer composition and in the polymer of the second polymer composition, whereby at least a portion of the compatibilizing agent reacts with the free radicals.
