Ultraviolet light stabilized copolyetherester compositions that comprise at least one nanoparticulate mineral selected from titanium dioxide, cerium oxide, and zinc oxide and at least one organic ultraviolet light stabilizer. Articles formed from the compositions are also disclosed.

Light stabilized copolyetherester compositions

This invention provides processes for preparing fiber or film comprising a polyurethane and layers delaminated from a lamellar clay, said layers being dispersed in said polyurethane. Fiber and film produced by the processes of the present invention exhibit reduced tack and an increased ability to affix at least one dye.

Process of making polyurethane fiber or film

This invention provides a fiber comprising a polyurethaneurea and layers delaminated from a lamellar clay, said layers being dispersed in said polyurethaneurea.

Polyurethane fibers and films

The addition of certain phosphate esters causes ethylene copolymers containing CaCO.sub.3 and/or Ca-Mg/CO.sub.3 and alumina trihydrate to have lower swell on burning and to have smaller and more uniform cell formation in the ceramic ash than compositions without such esters present.

Ethylene copolymers with enhanced fire resistant properties

The addition of melamine/formaldehyde resins causes ethylene copolymers containing CaCO.sub.3 and alumina trihydrate to have lower swell on burning and has smaller and more uniform cell formation in the ceramic ash than compositions without such resins present.
