Fibers made from alpha-olefin/vinyl or vinylidene aromatic and/or hindered cycloaliphatic or aliphatic vinyl or vinylidene interpolymers

The present invention pertains to fibers comprising: (A) from 50 to 100 wt percent (based on the combined weights of Components A and B) of at least one substantially random interpolymer having an I2 of from 0.1 to 1,000 g/10 min, a density greater than 0.9300 g/cm , and an Mw/Mn of 1.5 to 20; which...

More Information
Summary:The present invention pertains to fibers comprising: (A) from 50 to 100 wt percent (based on the combined weights of Components A and B) of at least one substantially random interpolymer having an I2 of from 0.1 to 1,000 g/10 min, a density greater than 0.9300 g/cm , and an Mw/Mn of 1.5 to 20; which comprises: (1) from 0.5 to 65 mol percent of polymer units derived from: (i) at least one vinyl or vinylidene aromatic monomer, or (ii) at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, or (iii) a combination of at least one aromatic vinyl or vinylidene monomer and at least one hindered aliphatic or cycloaliphatic vinyl or vinylidene monomer, and (2) from 35 to 99.5 mol percent of polymer units derived from ethylene and/or at least one C3-20 alpha-olefin; and (B) from 0 to 50 percent by weight (based on the combined weights of components A and B) of at least one takifier. The fibers of the present invention could have applications such as carpet fibers, elastic fibers, doll hair, personal/feminine hygiene applications,diapers, athletic sportswear, wrinkle free and form-fitting apparel, conductive fibers, upholstery, and medical applications including, but not restricted to, bandages, gamma sterilizable non-woven fibers.
