Abstract: A closure for a container is disclosed. The closure comprises a core member comprising at least one thermoplastic polymer, and at least one peripheral layer at least partially surrounding and intimately bonded to at least one surface of the core member, said peripheral layer comprising at least one styrene block co-polymer, wherein the core member has a density in the range of from about 100 kg/m3 to 350 kg/m3 and the peripheral layer has a density in the range of from greater than 350 kg/m3 to about 1,500 kg/m3 and a thickness in the range of from 0.15 mm to less than 0.50 mm.

Abstract: The disclosure relates to a synthetic closure for a product-retaining container constructed for being inserted and securely retained in a portal-forming neck of said container, said closure comprising at least a core member comprising at least one thermoplastic polymer, and at least one peripheral layer at least partially surrounding and intimately bonded to at least one surface of the core member, said peripheral layer comprising at least one thermoplastic polymer, wherein the synthetic closure is formed by extrusion, and at least one of the core member and the peripheral layer comprises a plurality of cells, and wherein the synthetic closure comprises cork powder.

Abstract: A synthetic closure for a product-retaining container is constructed for being inserted and securely retained in a portal-forming neck of said container, said closure comprising at least a core member comprising at least one cycloolefin-based copolymer.

Abstract: The present invention discloses a slurry loop reactor having at least two loops (1, 2) and comprising a by-pass line (11) connecting two points (12, 13) of the same loop reactor by an alternate route having a different transit time than that of the main route, said by-pass line also collecting the growing polymer of a first loop reactor (1) and sending said growing polymer to an entry point (13) in a second reactor (2).

Abstract: The present system discloses a transfer system devised in order to produce optimal flow from the first to the second loop reactor, by connecting the transfer lines to a by-pass line and by separating the connecting points of the transfer lines into the by-pass line by at least 70 cm.
