Автор: Aaron Essner, Aiguo Wang, John H. Dumbleton, Shi-Shen Yau
Принадлежит: Howmedica Osteonics Corp

A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part.

Rubber Composition Including an Expoxide Resin

Номер: US20120283360A1
Автор: Anne Veyland, José Carlos ARAUJO DA SILVA, Vincent Hunault
Принадлежит: Individual

A rubber composition which can be used in particular in tires, based on at least one diene elastomer, one reinforcing filler, one crosslinking system, between 1 and 20 phr of an epoxide resin and between 1 and 15 phr of an amine-comprising curing agent. The pair formed of epoxide resin with an amine-comprising curing agent advantageously replaces the pair formed of phenol/formaldehyde resin, which is a methylene acceptor, with the curing agent(s) HMT or H3M, which are conventional methylene donors. The use of this pair of reactants, epoxide resin and amine-comprising curing agent, makes it possible to obtain rubber compositions exhibiting a greater low-strain stiffness in comparison with conventional rubber compositions, without significantly damaging the hysteresis. Moreover, the combination of a phenolic resin, which is a methylene acceptor, with HMT or H3M, which is a methylene donor, produces formaldehyde during the vulcanization of the rubber composition. In point of fact, it is desirable to reduce, indeed even in the long run to eliminate, the formaldehyde of rubber compositions due to the environmental impact of this compound.

The membrane of wherein L comprises a fused ring structure including from 1 to 4 rings including at least one aromatic ring.3. The membrane of wherein L is selected from: phenylene claim 1 , biphenylene claim 1 , naphthalene and spirobisindane. The invention generally relates to thin film composite membranes (“TFC” membranes). Such membranes include a thin discriminating layer located upon a porous support. The invention specifically relates to the use of a polymer having intrinsic microporosity (“PIMs”) as the thin film layer. The subject membranes are generally useful in performing fluid separations and particularly useful in separations involving organic solvents or wide ranges of pH conditions.Polymers with intrinsic microporosity (PIMs) are characterized by having macro-molecular structures that are both rigid and contorted so as to have extremely large fractional free volumes. Examples include poly(1-trimethylsilyl-1-propyne) (PTMSP), poly(4-methyl-2-pentyne) (PMP) and polybenzodioxane (PIM-1). Because of their exceptional free volume, all are extremely permeable.
