Composite soft and resilient foams are manufactured by injecting a foamable mixture of polyisocyanates, polyols, water or inert blowing agents and, if appropriate, auxiliaries, under pressure into a mold of which about 90 to 30% of the volume is filled with foamed, soft and resilient particles of olefin polymers of particle size from about 3 to 50 mm and bulk density from 5 to 100 g/l -- these particles being in loose form or fused or stuck together -- and allowing the reaction mixture to foam up.

Manufacture of soft and resilient foams

Manufacture of molded articles of foamed ethylene copolymers containing, attached to the polymer chain, substituents having Zerewitinoff-active hydrogen atoms, and a binder mix containing isocyanate groups, wherein the components are mixed and the mixture is compressed in molds to from 80 to 20% of its original bulk volume and is cured under pressure.

Manufacture of molded articles of particulate foamed ethylene copolymers

Reversibly moisture-vapor-absorptive sheet materials and a process for their manufacture in which water-soluble polymers of vinyl ethers are combined with base materials and crosslinked thereon.
