This invention is concerned with spreadable fluid adhesive compositions, curable by conventional vinyl free radical polymerization or by exposure to a source of radiation, comprising a urethane prepolymer, at least one of dicyclopentyloxyalkyl acrylate and methacrylate, a polyol, and an effective amount of catalysts for curing of the urethane prepolymer and of the acrylate or methacrylate component. The invention is also concerned with a process for producing laminates of solid materials wherein the solid materials are adhered together by the adhesive composition.

Polyurethane adhesive compositions containing dicyclopentenyloxyalkyl

This invention relates to liquid adhesive and/or sealing compositions capable of hardening or curing under exclusion of oxygen comprising dicyclopentenyloxyethyl acrylate and/or methacrylate and an organic peroxy compound having 3 to 18 carbon atoms selected from the group consisting of organic peroxides and organic hydroperoxides, preferably the latter, and an imide or amine accelerator.

Anaerobic adhesive and/or sealing compositions comprising

The dye receptivity of polyolefin materials, used as backings for tufted surface coverings such as carpets and upholstery fabrics, is improved by coating the polyolefin material with a self-curing polymeric binder containing a quaternary ammonium salt. The backing is thereby easily dyed on-shade with the tufted face yarns so as to hide the backing.

Dyeable polyolefin backing for tufted surface coverings

The present invention is concerned with new and improved binders for the production of foamed or cellular articles which have a high degree of absorbency, and retain their bonded character as well as absorbency through numerous wash-dry cycles. The cellular articles are bonded by a novel self-cross-linking binder comprising a copolymer of (a) N-methylol-amine or -amide units, (b) sulfonic acid units which contain no basic nitrogen atoms or group, and (c) certain acrylic units of neutral but mildly hydrophilic character which contain no basic nitrogen atoms or group.
