  • Patent number: 5342887
    Abstract: The invention relates to a thermoplastic elastomer composition comprising a) a polyolefin and b) a crosslinked ethylene copolymer, the crosslinks between the main chains of the molecules of which have been formed of the hetero groups of at least two comonomer units being in different main chains and at least two hetero groups of the crosslinking-agent molecule being chemically attached to each other. The problem of such a mixture is that the lipophilic thermoplastic polyolefin and the ethylene copolymer to be crosslinked with its polar hetero groups are not compatible. Now, the problem has been solved by forming the crosslinks between the main chains so that either the hetero group of the comonomer unit in the main chain or then the hetero group of the crosslinking agent molecule always is a hydroxyl group, the hydroxyl group always forming a permanent oxygen crosslink bond with the other hetero group attached to it.
