A copolymer containing repeat units formed from the monomers (I) and (II), wherein each R.sup.1, if present, is independently hydrogen or hydrocarbyl; r is 0, 1 or 2; s is either 2 or 3; R.sup.2 R.sup.4 are each independently hydrogen or hydrocarbyl; R.sup.5 and R.sup.6 are each independently hydrogen, halo or hydrocarbyl; P.sub.d.sup.- is the anion formed by loss of a proton from a proton donating group P.sub.d--H; Z is either a bond or hydrocarbyl; R.sup.7 and R.sup.8 are each independently hy...
The invention relates to novel crosslinkable copolymers which are obtainable by (a) copolymerizing at least one hydrophilic monomer having one ethylenically unsaturated double bond and at least one crosslinker comprising two or more ethylenically unsaturated double bonds in the presence of a chain transfer agent having a functional group; and (b) reacting one or more functional groups of the resulting copolymer with an organic compound having an ethylenically unsaturated group.The crosslinkable ...

A polymer having a plurality of 5 6 membered unsaturated rings which may be the same or different, linked together by way of linker chains to form a backbone, at least some of said 5 6 membered unsaturated rings carrying a ligand. Polymers of this nature can act as DNA mimics and as supports for use in oligonucleotide production.
A method of production of a homopolymer or copolymer or homo-oligomer or co-oligomer product characterised in that the product is obtained by condensation reaction of a diaminoanthracene, substituted or not, optionally with a diiminoanthracene substituted or not in the absence of anthraquinone substituted or not.
The invention provides (co)polymers having the formula (I): ##STR1## wherein M is hydrogen, a metal ion or an ammonium cation; x is 1, 2 or 3; y is an integer from 2 to 100; and n is 1, 2 or 3. The (co)polymers of formula I are corrosion and/or scale inhibitors for the protection of metal surfaces in contact with water.
The invention relates to novel polyallyl amine polymers having a weight average molecular weight of at least 2000 that, based on the number of amino groups of the polyallyl amine, comprises from approximately 1 to 99% of units of formula ##STR1## wherein R is as defined in the claims. The novel polyallyl amine polymers are useful, for example, for the surface-modification of different substrates or may be used for the manufacture of biomedical mouldings.
There are disclosed polymeric or oligomeric product obtainable from the reaction of an anthraquinone with an aromatic diamine, characterised in that the anthraquinone is substituted or is not substituted and in that the diamine is a diamino anthracene which is substituted or is not substituted. The anthraquinone may be of the general formula (I): ##STR1## where, R may be the same as or different to R', and may be a hydrogen atom (when R=R'=H, the compound is anthraquinone), or CH.sub.3, CH.sub.3...
