摘要: A process for producing thermoplastic vulcanizates, the process comprising (i) dynamically vulcanizing a rubber with a curative in a first stage, where the rubber is within a blend that includes the rubber, a thermoplastic resin, and the curative, where said step of dynamically vulcanizing occurs at a temperature at or above the melting point of the thermoplastic resin, where said step of dynamically vulcanizing employs a peroxide curative, and where said rubber includes polymeric units deriving from 5-vinyl-2-norbornene, (ii) continuing said step of dynamically vulcanizing to cause phase inversion of the blend to thereby convert the thermoplastic resin into a continuous phase, (iii) maintaining the blend at or above the melting point of the thermoplastic resin after the phase inversion, and (iv) introducing molten thermoplastic resin into the blend in a second stage, where said step of introducing molten thermoplastic resin occurs after phase inversion but before the blend is cooled to a temperature below the melting point of the thermoplastic resin.

摘要: The invention relates to a method of preparing a thermoplastic vulcanizate comprising: a) melt processing a blend of thermoplastic polymer and vulcanizable elastomer in a multi-screw extruder having at least three intermeshing screws, wherein said screws have 3-170 mixing zones, and said extruder having a L/D ratio of 15-100, and a screw profile that has 3 to 17 meshes per L/D; b) adding at least one curing agent to the melt-processed blend of a) in at least one location in the first 46% of the length of said extruder, or adding at least one curing agent to the melt-processed blend of a) in a second extruder, so as to initiate curing of the blend: and, curing at least partially said elastomer by reactive melt processing. Improved processing, reaction kinetics and efficiencies are achieved, as well as thermoplastic vulcanizate products having decreased weight gain when placed in mineral oils.

摘要: A method of forming a finished film comprising extruding a molten polyethylene comprising a diene terpolymer modifier through a die opening to form a film, wherein the diene terpolymer modifier is a terpolymer comprising ethylene-derived units, C
3 to C
10 α-olefin derived units, and diene-derived units; causing the film to progress in a direction away from the die opening; cooling the film at a distance from the die opening, the distance adjusted to allow relaxation of the molten polyethylene prior to solidification and/or crystallization upon cooling; and isolating a finished film therefrom. Desirably, the polyethylene is a linear low density polyethylene, and the die and cooling is suitable for forming a blown film.摘要翻译: 一种形成成品薄膜的方法,包括通过模头开口挤出包含二烯三元共聚物改性剂的熔融聚乙烯以形成薄膜,其中二烯 - 三元共聚物改性剂是包含乙烯衍生单元,C3-C10-α-烯烃衍生单元, 和二烯衍生单元; 导致膜在远离模具开口的方向上前进; 在离开模具开口一定距离处冷却膜,调节该距离以允许在冷却之前固化和/或结晶之前使熔融聚乙烯松弛; 并从其中分离成品薄膜。 理想地,聚乙烯是线性低密度聚乙烯,并且模具和冷却适合于形成吹塑薄膜。
