    • An end-group functionalized polymer having one or more end groups according to the general formula (I) wherein R1 represents a saturated or unsaturated, linear or branched, preferably aliphatic, hydrocarbon group having from 1 to 20 carbon atoms which, in addition to C and H, may contain one or more heteroatoms, preferably independently of one another selected from O, N, S or Si; R2, R3 are identical or different and represent saturated or unsaturated hydrocarbon groups having from 1 to 20 carbon atoms and wherein the hydrocarbon group may contain, in addition to C and H atoms, one or more heteroatoms, preferably selected from the group consisting of O, N, S and Si; A represents a residue selected from the group consisting of O-R4-OH, R5-OH and R6-NH- R7, preferably O-R4-OH wherein R4, R5 and R6 represent a saturated or unsaturated linear or branched hydrocarbon group which, in addition to C and H atoms, may contain one or more heteroatoms, independently selected from O, N, S or Si and which contains from 1 to 20 carbon atoms and wherein R7 represents H or a linear or branched or cyclic aliphatic or aromatic hydrocarbon group having from 1 to 20 carbon atoms and which, in addition to C and H atoms, may contain one or more heteroatoms, preferably selected from O, N, S or Si; and wherein the polymer is a homopolymer of a conjugated diene or a copolymer of at least one or more conjugated diene and one or more vinylaromatic monomer and, optionally one or more other comonomers. Also provided are a process for making the polymers and articles made with the polymers.

    • A process for making a functionalized diene polymer terminated by a functional end group selected from thiol containing end groups, thiolate containing end groups and a combination thereof, comprising (i) preparing a diene polymer by a polymerization reaction comprising an anionic polymerization reaction; (ii) adding at least one first functionalisation reagent according to formula (III) to the polymerization reaction and reacting the at least one first functionalisation reagent with the anionic chain ends of the diene polymer to obtain a first reaction product, (iii) adding at least one second functionalising reagent (IV) to the first reaction product to produce a thiol-terminated or thiolate-terminated diene polymer; wherein the process, optionally, further comprises (iv) isolating the thiol-terminated or thiolate-terminated diene polymer from the reaction mixture, and optionally further comprising (v) bringing the diene polymer into the form of sheets, bales, granules, bales or into the form of a powder, wherein the thiol-terminated or thiolate-terminated diene polymer contains at least 51% by weight based on the total weight of the polymer of units derived from 1,3-butadiene, and wherein in formula (III) and (IV) R1, R2, R3 and R4 represent, independently from each other, hydrogen or a hydrocarbon residue containing from 1 to 24 carbon atoms per unit n and wherein the hydrocarbon residue may be saturated or may contain at least one carbon-carbon double bond and wherein the hydrocarbon residue may be interrupted once or more than once by O, Si or S atoms and may contain one or more substituents selected from alkyl amino, alkyl phosphino, alkyl silyl substituents and combinations thereof; R5 represents an alkylene group -[CXY]p- wherein p is an integer selected from 2, 3, 4 or 5 and X and Y are independent from each other selected from H, or C1-C6 alkyl and each X and Y may be the same or different in each unit p, or the alkylene group is unsaturated in which case two neighbouring X, or two neighbouring Y, or one neighbouring X and one neighbouring Y jointly represent a carbon-carbon double bond; n represents 3, 4, 5, 6, 7 or 8; x and y are selected independently from each other and either represent 0 or 1 with the proviso that the sum of x+y is either 1 or 2. Also provided are polymers obtained by the process, compositions and compounds containing the polymers and articles made from the compounds. Also provided are methods of making compounds and articles.
