Thermoplastic elastomers

A thermoplastic elastomer consisting essentially of a copolymer comprising a mixture of ethylene; one or more alpha-olefins having 3 to 12 carbon atoms; and, optionally, a diene, said copolymer being in an uncrosslinked state and having a crystallinity in the range of about 2 to about 40 percent by...

More Information
Summary:A thermoplastic elastomer consisting essentially of a copolymer comprising a mixture of ethylene; one or more alpha-olefins having 3 to 12 carbon atoms; and, optionally, a diene, said copolymer being in an uncrosslinked state and having a crystallinity in the range of about 2 to about 40 percent by weight based on the weight of the copolymer wherein about 15 to about 85 percent by weight of the crystallinity melts at a temperature above 80 DEG C ; about 15 to about 85 percent by weight of the crystallinity melts at a temperature below 80 DEG C; and the crystalline melting temperatures differ by at least about 30 DEG C.
