Abstract: The present invention relates to a furan moiety-containing olefin copolymer and a process for preparing the same, and to a reversible crosslinked or functionalized olefin copolymer. The reversible crosslinked olefin copolymer as described therein performs as a thermoset material in use while still demonstrates the processability like traditional thermoplastics. The de-crosslinking process is triggered at higher temperature, which enables the material with good processability. While cooling down, crosslink would be further reformed and provides higher strength, better elasticity, resilience etc.

Abstract: The present invention relates to a functional cyclic olefin polymer obtained from hydrogenation of a cyclic olefin polymer, wherein the cyclic olefin polymer comprises at least a monomeric unit A? derived from a monomer A having a norbornene ring and a polar functional group, wherein the amount of the monomeric unit A? is in the range of from 20% to 100% by mole, 50% to 100% by mole, from 60% to 100% by mole, or from 70% to 100% by mole, based on the total amount of the monomeric units of the cyclic olefin polymer. The present invention further relates to a process for producing the functional cyclic olefin polymer, a composition comprising the functional cyclic olefin polymer, and the use of the functional cyclic olefin polymer. The functional cyclic olefin polymer of the present invention exhibits improved properties, especially in terms of mechanical properties and barrier properties.

Abstract: A reversible epoxy polymer obtainable by the reaction between at least one epoxy compound and at least one curing agent, wherein at least part of the epoxy compound contains one reversible borate moiety or derivative thereof per molecule; and/or at least part of the curing agent contains one reversible borate moiety or derivative thereof per molecule; and/or the reaction system further comprises at least one compound containing hydroxyl and epoxy group and at least one BQH-containing compound or its ester derivative, wherein said BQH-containing compound contains two or more B-QH moieties, and wherein the derivative of borate moiety represents a moiety with the oxygen in the borate moiety being replaced with other element of the sixth main group and wherein each Q is independently an element of the sixth main group.

Abstract: Disclosed are films, and methods of making such films, the films comprising a first polyethylene and a hydrocarbon resin, which can provide improved friction performance. The hydrocarbon resin may be incorporated in neat form or as a blend, for instance with a second polyethylene that may be the same as or different from the first polyethylene.
