A polymer comprising a bulk polymer or copolymer PB together with an amount of a polymer-dendron additive D-PD of formula (I): is provided, such that the polymer comprises from 0.001 to 50% of dendron-additive D-PD calculated as weight of dendron D in polymers D-PD and PB, wherein: PD is a polymer chain comprising at least one monomer repeat unit and is cyclic (having no ends) or has at least two ends and is linked to group Y in chain or at least one of its ends; Y is a linking group; a and b are each zero or a whole number integer in the range from 1 to 5; A is a branching group; each XZ1 is a functional group independently selected from one or more of OH, halo, amino, cyano, carboxylic acid, ester, thiol, silane, azide, alkyl, alkenyl, alkynyl, oligoalkyl, oligoalkenyl, oligoalkylether or any organometallic group, a linear, branched or cyclic C1-20 alkyl, alkenyl or cycloalkyl group optionally comprising a heteroatom O or S and comprising from 3 to 37 functional groups selected from halo, OH, NR2, CN, COOH, COOR, SR, SiCl3, SiRCl2 SiR2Cl, Si(OR)3, and a combination thereof; Z is O or S; is derived as functional groups as hereinbefore defined; G indicates the Generation of a given dendron, in which both a (where present) and b are in the range 1 to 5. |
