摘要： A thermoplastic elastomer with increased oil resistance and decreased compression set compared to conventionally cured thermoplastic elastomers may be made from a dynamically vulcanized blend of propylene resin and ethylene/alpha-olefin/non-conjugated diene elastomers via a curing system containing a free radical initiator, a first co-agent including diene-containing polymers with a 1,2-vinyl content greater than 50% by weight, and a second co-agent including multifunctional acrylates containing at least two acrylate groups, multifunctional maleimides containing at least two imide groups, or mixtures of both, where the elastomer gel content in the modified blend is at least 97%.

摘要： This invention is based upon the discovery that elongated silica has superior characteristics for reinforcing rubbery elastomers as compared to conventional silica. More specifically, elongated silica provides a higher level of reinforcement for elastomers at the same level of loading. Accordingly, elongated silica can be employed to attain an equivalent level of reinforcement at a lower level of loading. This results in lower weight compositions and potential cost savings. Rubber compounds that are reinforced with elongated silica offer significant advantages in tires including reduced rolling resistance, increased tread life, and, of course, reduced weight. The subject invention more specifically relates to a tire having a tread wherein said tread is comprised of a silica reinforced rubber composition, wherein the silica reinforced rubber composition is comprised of (1) a rubbery polymer and (2) an elongated silica, wherein the elongated silica has a width that is within the range of about 5 nm to about 40 nm, and wherein the elongated silica has a length of about 40 nm to about 300 nm. The present invention also discloses a process for preparing a silica reinforced rubber composition which comprises (1) adding an elongated silica to a latex of a rubbery polymer, and (2) recovering the silica reinforced rubber composition from the latex.

摘要： This invention is based upon the unexpected discovery that ethyl lactate can be used as an emulsifying/dispersing excipient for numerous biologically active compounds without destroying the pharmacological activity of the active ingredient. Ethyl lactate proves to be an extremely effective agent for solubilizing biologically active compounds that are difficult to solubilize in conventional excipients. The operability of this invention is predicated on the necessity for the ethyl lactate to be essentially free of peroxide compounds. Such pharmaceutical grade ethyl lactate can be made by reducing the level of peroxide compounds in high purity ethyl lactate by hydrogenation, reduction with a non-catalytic chemical reducing agent, absorption into activated carbon or alumina, or distillation. In any case, it has been determined to be critical for the level of peroxide compounds to be reduced to less than 10 ppm for the pharmaceutical grade ethyl lactate to be viable as an excipient for many biologically active ingredients. The present invention more specifically discloses a pharmaceutical composition which is comprised of a biologically active ingredient wherein said biologically active ingredient is dispersed in ethyl lactate and wherein said ethyl lactate contains no more than 10 ppm of peroxidic materials and maintains a Gardner 1 color rating throughout its shelf-life period.
摘要翻译：本发明基于意想不到的发现，乳酸乙酯可用作许多生物活性化合物的乳化/分散赋形剂，而不破坏活性成分的药理活性。乳酸乙酯被证明是增溶难溶于常规赋形剂的生物活性化合物的非常有效的药剂。本发明的可操作性取决于乳酸乙酯基本上不含过氧化物的必要性。这样的药物级乳酸乙酯可以通过氢化，通过非催化化学还原剂还原，活性炭或氧化铝的吸收或蒸馏来降低高纯度乳酸乙酯中的过氧化物化合物的水平来制备。在任何情况下，已经确定，对于药物级乳酸乙酯作为许多生物活性成分的赋形剂而言，将过氧化物化合物的水平降低至小于10ppm是至关重要的。本发明更具体地公开了一种药物组合物，其由生物活性成分组成，其中所述生物活性成分分散在乳酸乙酯中，并且其中所述乳酸乙酯含有不超过10ppm的过氧化物质，并且在其整个过程中保持加德纳1的颜色等级保质期。
