Abstract: An amphiphilic block copolymer having any one of the formulas D-S—H, S(D)-H, S—H(D), D-S—H—S, D-S—H—S-D, S(D)-H—S, S(D)-H—S(D) or S—H(D)-S is disclosed. S is a hydrophilic block; H is a hydrophobic block; D is a drug molecule; ( ) denotes that the group is bonded directly or indirectly as a side chain or as part of a side chain group to the adjacent group; and the hyphen, “-” (or sometimes “-”), denotes that each of the adjacent S, H or D are linked either directly to one another or indirectly to one another via a linker, additionally wherein the hydrophilic block comprises a first hydrophilic monomer and the hydrophobic block comprises a first hydrophobic monomer and a second hydrophobic monomer.

Abstract: A star polymer of formula O[P1]-([X]-A[P2]-[Z]-[P3])n where O is a core; A is a polymer arm attached to the core; X is a linker molecule between the core and the polymer arm; Z is a linker molecule between the end of the polymer arm and P3; P1, P2 and P3 are each independently one or more pharmaceutically active compounds that act extracellularly or intracellularly, n is an integer number; [ ] denotes that the group is optional; and at least one of P1, P2 or P3 is present.

Abstract: A method of separation of hydrogen from gas mixtures consisting in that a gas mixture (3) with any hydrogen content is introduced into a closed space (4), in which a polymer foam (1) containing non-communicating pores (2) is placed. Due to the fact that the hydrogen partial pressure in pores (2) of the polymer foam (1) is lower, hydrogen penetrates into the pores. Hence, the gas mixture (3) leaving the closed space (4) is deficient in the hydrogen. The inlet of the gas mixture (3) into the closed space (4) can be interrupted at the time when the leaving mixture has the same composition as the introduced gas mixture (3) or earlier. Then the pressure in the closed space (4) is decreased and, due to the leveling of its partial pressure, hydrogen is released from the polymer foam (1) and can be received for further use. Its concentration is higher than in the starting gas mixture (3).
