A poly(diallylamine)polymer pharmaceutical composition or pharmaceutical derivate used to sequester bile acid and/or to reduce serum cholesterol levels. The polymer is derived from a monomer of formula Ia, where Ris a bridging group of valency r, and r is an integer of 3 or greater to provide a cross linked polymer, and all diallyl nitrogen atoms are linked to at least two further diallyl nitrogen atoms. 

Use of poly diallyamine polymers

An adhesive or sealant composition comprising a compound of formula (I) provided that at least one of (a) Rand Ror (b) Rand Ror (c) Rand Rincludes an electron withdrawing group; and where necessary, a polymerisation initiator. Novel compounds of formula (I) are also described and claimed. Adhesive compositions can be used to bond for example glass and metal surfaces. Certain biocompatible adhesives for medical applications are included.

Adhesives and sealants

The use of a compound of formula (A), which comprises a group of sub-formula (I) where R, R, R, R, R, R, Xand Yare various specified organic groups wherein at least one of said groups has sufficient electron whitdrawing properties to activate the multiple bonds to polymerisation, in a stereolithographic composition. Stereolithographic applications of these compounds are also described and claimed.

Use of a composition in stereolithography

An adhesive or sealant composition comprising a compound of formula (I) provided that at least one of (a) R and R or (b) R and R or (c) R and R includes an electron withdrawing group; and where necessary, a polymerization initiator. Novel compounds of formula (I) are also described and claimed. Adhesive compositions can be used to bond for example glass and metal surfaces. Certain biocompatible adhesives for medical applications are included.

Diallylamine monomers and network polymers obtained therefrom

A method for producing a polymeric material, said method comprising subjecting a starting material which includes two multiple bonds which are activated so that they will take part in a polymerisation reaction and wherein the multiple bonds are sufficiently close togeter to ensure that cyclopolymerisation will preferentially occur; to suitable conditions under which said polymerisation reaction will occur, provided that the starting marerial is other than triallyamine hydrochloride. The method can be used to produce polymers for various processes including adhesives, network polymers, liquid crystal polymers etc.

Polymer production

This invention describes a method for the loading and alignment of elastomers in electro-optic and electro-active devices. It comprises the in-situ polymerization between substrates of liquid crystal monomers in the presence of cross-linking reagents. It also describes the production of free-standing elastomer films.
