More Information
Summary:The present invention pertains to elastic films having at least one layer comprising a substantially random interpolymer or a blend thereof. The interpolymer comprises polymer units derived from at least C2-20 alpha-olefin and (i) at least one vinyl aromatic monomer, or (ii) at least one aliphatic or cycloaliphatic vinyl or vinylidene monomer, or (iii) a combination of at least one aromatic vinyl monomer and at least one aliphatic or cycloaliphatic vinyl or vinylidene monomer. The interpolymer may also comprise one or more ethylenically unsaturated polymerizable monomers other than those previously mentioned. The elastic films have a recovery in the cross direction of greater than or equal to about 80% and has a recovery in the machine direction of greater than or equal to about 60%.
