Abstract
Amorphous and impact resistant co/ter-polymer made from olefins and aryl-substituted cyclic monomers by polymerizing using a catalyst, wherein the substituent is a phenyl- or indanyl-group and the catalyst is a metallocene-catalyst. Preferably said aryl-substituted cyclic monomer is phenyl-norbomene (5-phenyl-bicylo-2,2,1-hept-2-ene) or indanyl-norbomene (1,4-methano-1,4,4a,9a-tetrahydrofluorence).
