Abstract: 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 R6 is 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.

Abstract: An adhesive or sealant composition comprising a compound of formula (I) provided that at least one of (a) R1 and R6 or (b) R2 and R3 or (c) R4 and R5 includes 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.

Abstract: An electrochromic arrangement particularly useful in a region of the infra-red spectrum above 3 microns comprises in order a rear glass substrate (1), a film electrode (2) with an IR reflectivity of at least 50%, an ion storage layer (3) an ion conducting layer (4). An electrochromic tungsten oxide layer (5) having at least a degree of crystallinity, a silicon front electrode (6) and an antireflection coating (7). In the uncharged state of layer (5) all layers (3-7) are transparent and most incident light is reflected at (2). On entering the charged state the layer (5) exhibits a marked increase in light absorptivity and refractive index. In a device incorporating a bare layer (5) the latter causes such a large increase in reflectivity at the front surface that the increase in light absorption tends to be masked, with a resulting increase in reflectivity of the device.

Abstract: Compounds of the formula: having two double bonds which are activated so that they will take part in a polymerization reaction, the double bonds being sufficiently close together to ensure that cyclopolymerization will preferentially occur. These compounds are used as monomers which preferentially are cyclopolymerized under the influence of ultraviolet or thermal radiation in the production of network polymers, for example coatings or binders.

Abstract: 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.
