Elastic fibers are described that comprise (i) a polyolefin polymer, e.g., a homogeneously branched, preferably substantially linear, ethylene polymer, and (ii) a photoinitiator, e.g., an aromatic ketone, in an amount sufficient to effect at least a partial cross-linking of the polymer when the fiber is exposed to sufficient UV-radiation to activate the photoinitiator. Articles, e.g., fabrics, comprising fibers of this invention, either alone or in combination with one or more other fibers, e.g., cellulose, nylon, etc., exhibit good heat resistance and elasticity at elevated temperatures.

Crosslinked elastic fibers

Fully diluted hard surface cleaners are disclosed which are particularly effective on cleaning soap scum. The cleaners contain at least 0.45 eq/kg of a dissolved anion which reacts with calcium ion to form an insoluble salt. The cleaners also contain a particular amine oxide, or a different surfactant in conjunction with a solvent. Preferred embodiments include a bleach, which provide for a cleaner which is effective on soap scum and mold and mildew.

Fully diluted hard surface cleaners containing high concentrations of certain anions

A water-soluble polymer having a low polydispersity index and controlled molecular weight can be prepared by oxidative degradation and shearing of a water-swellable crosslinked polymer or by hydrolysis of the crosslinked polymer to a high molecular weight soluble polymer, followed by oxidative degradation of the high molecular weight polymer.
