摘要： The disclosure relates to thermally reversibly crosslinked polyolefins (TRC-PO) and methods for making the same. A TRC-PO can be formed by reactive melt-processing a mixture including (i) a polyolefin, (ii) an initiator, and (iii) a reversible crosslinker. The reversible crosslinker includes (A) a grafting agent moiety selected from unsaturated cyclic anhydrides, unsaturated cyclic imides, cyclic nitroxides, and ring-opened analogs thereof, and (B) a crosslinking moiety bound to the cyclic grafting agent moiety. This reactive melt-processing, for example including reactive extrusion, forms a thermally reversibly crosslinked (TRC) polyolefin with polyolefin chains reversibly crosslinked via the reversible crosslinkers, which provide dynamic covalent bonds, such as siloxanes and esters, that are amenable to melt re-processing to re-from or otherwise re-use the TRC-PO while still retaining the reversible crosslinks after re-processing. Catalysts and additives such as rheology modifiers can be added to the melt-processing mixture.

摘要： A rubber composition comprising 0.1 to 2.5 parts by weight of a lubricant having a flow temperature of 50 to 100° C. based on 100 parts by weight of an ethylene/butene/5-ethylidene-2-norbornene terpolymer. This rubber composition is compounded with a specific lubricant, has the following effects. That is, the rubber composition prevents difficulties caused by sticking between unvulcanized rubber compound, improves productivity in the rubber compound preparation process and the vulcanization molding process of crosslinked molded products, such as seal members, and does not impair the low temperature properties of the crosslinked molded products. This rubber composition is effectively used as a crosslinking molding material for seal parts, for which a high pressure gas sealing function is particularly required in a low temperature environment, e.g., −39° C. or lower.

摘要： The present invention relates to the use of at least one N,N-dimethylamide as an additive in an elastomeric composition for producing a tread band for vehicle wheels, wherein the N,N-dimethylamide has the formula: formula (I), wherein: R is a C6-C12 alkyl group, and R′ and R″ are methyl. A further aspect of the present invention concerns a vulcanised elastomeric material for producing a tread band for vehicle wheels obtained by vulcanising an elastomeric composition comprising (a) at least one elastomeric polymer, (b) at least one reinforcing filler selected among hydroxides, oxides and hydrated oxides, salts and hydrated salts of metals or mixtures thereof and (c) at least one N,N-dimethylamide of formula (I). An additional aspect of the present invention concerns a tread band for vehicle wheels comprising a vulcanised elastomeric material, which vulcanised elastomeric material is obtained by vulcanising an elastomeric composition comprising (a) at least one elastomeric polymer, (b) at least one reinforcing filler selected among hydroxides, oxides and hydrated oxides, salts and hydrated salts of metals or mixtures thereof and (c) at least one N,N-dimethylamide of formula (I).
