Process for the preparation of an impact-resistant polymer composition

An impact-resistant polymer composition exhibiting improved impact resistance at no loss in creep is obtained by melt-mixing a solid matrix polymer A with a solid composition containing the rubber composition dispersed in a matrix polymer B. The dispersion of rubber composition in matrix polymer B i...

Beschreibung
Zusammenfassung:	An impact-resistant polymer composition exhibiting improved impact resistance at no loss in creep is obtained by melt-mixing a solid matrix polymer A with a solid composition containing the rubber composition dispersed in a matrix polymer B. The dispersion of rubber composition in matrix polymer B is obtained by melt mixing the matrix polymer B with a rubber composition which includes a functionality rubber and a non-functionality rubber. The amounts of the components are such that the impact-resistant polymer composition contains 0.5 to 75 parts by weight of the rubber composition per 100 parts by weight of the matrix polymers A and B. The composition may be used in various applications, including plugs, heat bridges for aluminum windows, hammer heads and the like.
