Abstract: Block copolymers comprise: (a) at least 3 blocks A, built up from at least 3 of varying monomer constitutional units, each block being only directly connected with blocks with which it is incompatible; and (b) end blocks E and E , different from each other, the end block E developing attractive molecular interaction with the end block E .

Abstract: In a method for the production of linear block copolymers, which contain at least a sequence A-B-C of a block A of radically polymerizable monomers (a), a block B of monomers (b) and a block C of radically polymerizable monomers (c), the monomers (a), (b) and (c), which are different from each other, are made to react with (1) radical polymerization of monomers (c) with a macro radical initiator (I) of general formula Y-B-X-B-Y, in which X and Y are divisible functional groups upon formation of radicals, whereby X can be separated without fission from Y, under conditions leading to the formation of macro radical initiators (II) which contain the sequence Y-B-C, by selectively separating X and by polymerizing (c), (2) radical polymerization of monomers (a) with the macro radical initiator (II) by separating Y and forming linear block copolymers containing the sequence A-B-C. The block copolymers have the sequences A-B-C, A-B-C-B-A, C-B-A-B-C or A-B-C-B-A-B-C-B-A.

Abstract: The selective hydrogenation of a block terpolymer (I) consisting of a block (A) consisting of conjugated diene monomers, a block (B) consisting of vinylic or olefinic monomers containing a functional group and a block (C) consisting of a vinyl aromatic monomer is claimed. Block (A) is selectively hydrogenated using hydrogen in the presence of a RhCl(P(C6H5)3)3 or RuCl(P(C6H5)3)3 catalyst.Also claimed are: (i) the resulting hydrogenated block copolymer (ii) moulded articles, film or fibres containing the hydrogenated block copolymer.

Abstract: Multiphase polymer mixtures contain (a) a polymer (A); (b) an A-B block copolymer (B) made up of a block A and of an elastic block B; (c) a B-C block copolymer (C) made of an elastic block B and of a block C; and (d) at least another polymer (D) which is different from (A), (B) and (C) and incompatible with polymer (A). Blocks A, B and C differ from each other, polymer (A) is compatible with block A and incompatible with block C, polymer (D) is compatible with block C and incompatible with block A, elastic block B has a glass transition temperature below +20 DEG C and blocks A, B and C are incompatible with each other.
