Described herein are substantially linear copolymeric compositions having at least two azide groups and at least two non-activated acetylene groups. The azide groups and the non-activated acetylene groups are reacted to cure the substantially linear copolymer composition. Also, described are methods of making and using such substantially linear copolymeric compositions.

Polymeric compositions and method of making and articles thereof

Compositions having a fluoropolymer with a nitrile-containing cure site and at least a) a mono azide with at least one functional group in the beta position, or b) a polyazide, as a curing agent as well as methods and articles thereof are described. Articles of this disclosure are found to exhibit excellent chemical resistance and thermal stability.

Fluoropolymer compositions and method of making and using thereof

A method for aqueous bead-type suspension polymerization of (meth)acrylic monomers to prepare non-agglomerating, storage stable (meth)acrylic polymer beads which are extrudable at low temperatures. The invention also relates to the polymer beads and to their use as adhesive, in particular as a pressure sensitive adhesive. The invention also discloses adhesive compositions comprising the polymer beads.

Method of suspension polymerization of (meth)acrylic monomers using dextrin, and polymer beads resulting from that method

The present invention provides a radiation curable vinyl-silicone pressure-sensitive adhesive composition which combines the advantages of silicone and acrylate pressure-sensitive adhesives and which does not experience gross phase separation problems. The composition comprises at least about 20 weight percent of a certain telechelic silicone polymer, about 0.5 to about 80 weight percent of monofunctional free-radically polymerizable vinyl monomer copolymerizable with the silicone polymer, and a sufficient amount of a silicate MQ tackifying resin to impart a degree of adhesive tack to the cured composition at the use temperature, wherein the weight percentages of the silicone polymer and the monomer are based upon the total weight of the silicone polymer and monomer.

Radiation-curable acrylate/silicone pressure-sensitive adhesive

Novel pressure-sensitive adhesives are described which show significant resistance to solvents and working fluids such as jet fuel, hydraulic fluid, de-icing fluid and the like. Adhesive compositions comprise nonaqueous dispersions of copolymers of acrylic monomers prepared in the presence of a vinyl-substituted fluoroalkyl siloxane having the general formula I and a macromonomeric stabilizer. The adhesives prepared from the adhesive compositions exhibit excellent adhesion to glass, aluminum, and low surface-energy materials such as fluoroalkyl siloxane elastomers. The fluoroalkyl siloxane has the formula ##STR1##

Radiation-curable silicone elastomers and pressure sensitive adhesives

A method of using a pressure sensitive adhesive to form a moisture resistant, water-dispersible tape is provided. The adhesive and tape are resistant to autoclavation conditions and/or moisture and body fluids during usage, and are water-dispersible when immersed in aqueous solutions. The tape may be used with cloth body coverings, such as garments such as hospital gowns, drapes, dressings, diapers and other body coverings which require cloth to cloth or cloth to skin adhesion in the presence of moisture and bodily fluids yet be dispersible from such body coverings during laundering or other aqueous alkali immersion.
