The presently claimed invention is directed to a copolymer obtained by reacting at least one isocyanate (A) comprising at least one allophanate group and at least one active double bond with at least one isocyanate reactive component (B) to form an intermediate product (C); and reacting the intermediate product (C) with at least one active double bond reactive component (D) to obtain the copolymer which can be used as dispersant. The at least one isocyanate reactive component (B) is selected from the group consisting of monofunctional polyether amine (B1), monofunctional polyether alcohol (B2), C.sub.6-C.sub.30 monofunctional alcohol (B3) and monofunctional polyester alcohol (B4).

The present invention also provides a thermosetting conductive adhesive that has excellent adhesive strength when cured at a high temperature in a short time. The thermosetting conductive adhesive according to the present invention includes components (A) to (D): component (A): a urethane-modified polyfunctional (meth)acrylate oligomer that is either an aromatic urethane-modified (meth)acrylate oligomer having six (meth)acryl groups in the molecule or an aliphatic urethane-modified (meth)acrylate oligomer having two (meth)acryl groups in the molecule; component (B): a monofunctional (meth)acrylate monomer; component (C): an organic peroxide; and component (D): conductive particles, in which when the component (A) is an aliphatic urethane-modified (meth)acrylate oligomer having two (meth)acryl groups in the molecule, the component (B) is a monofunctional acrylate monomer.

This disclosure relates generally to a moisture curable composition. The composition includes a first, crosslinkable copolymer having a plurality of silyl alkoxy terminal groups and a backbone that is the reaction product of a diisocyanate and a mixture of a low molecular weight polyether polyol and a high molecular weight polyether polyol; a second crosslinkable oligomer having a plurality of silyl alkoxy terminal groups and a backbone that is the reaction product of a diisocyanate and a low molecular weight polyether polyol; and a third crosslinkable oligomer having a plurality of silyl alkoxy terminal groups and a backbone that is the reaction product of a diisocyanate and a high molecular weight polyether polyol.

Switchable adhesive compositions are disclosed comprising an adhesive component, which is formed from a material or materials capable of undergoing cross-linking with isocyanale other than by free radical polymerisation and at least one isocyanate having an average of more than one isocyanate functions, unsaturated curable molecules mixed in or partially bound in with the adhesive component, or unsaturated curable moieties fully bound in to the material or materials capable of undergoing cross-linking with isocyanate, and a photoinitiator. The adhesive composition forms a tacky gel-like pressure sensitive adhesive that is capable of moulding to a substrate, and upon activation of the photoinitiator the curable molecules or moieties cross-link to form a dense 3-dimensional network through the adhesive component which causes the composition to become less tacky and to form an elastic film with reduced peel strength.
