    Abstract: Disclosed herein are a highly uniform spandex and process for making such spandex. More particularly, the polyurethaneurea of which such spandex is prepared has both dialkylurea and cycloalkylurea ends, wherein a chain terminator composition includes a dialkylamine such as diethylamine and a cylcoalkylamine such as cyclohexylamine.

    Abstract: An improved spandex fiber is provided that is particularly useful for use in tricot-knit fabrics with nylon yarns. The fiber is formed from a polyether-based spandex polymer made from a poly(tetramethylene ether) glycol of about 2,200 molecular weight which was capped with methylene-bis(4-phenylisocyanate) and the resultant product then chain extended with a diamine mixture of ethylene diamine and 2-methyl-1,5-pentanediamine in a molar ratio of about 70/30.
