    • The invention includes a process comprising (a) forming a polymeric admixture including at least one polyolefin which has been prepared using a single site catalyst and at least a crosslinking amount of at least one poly(sulfonyl azide) crosslinking agent; (b) shaping the resulting admixture; and (c) heating the resulting shaped admixture to a temperature at least the decomposition temperature of the crosslinking agent. The steps take place in any sequence and optionally include substeps. The single site catalyst is preferably a constrained geometry or metallocene catalyst, but optionally another transition metal catalyst which is not a traditional Ziegler Natta Ti/MgCl2 catalyst such as a vanadium catalyst. The invention further includes all compositions obtainable by the process of the invention as well as all articles formed from these compositions. The articles are preferably thermoformed, compression molded, injection molded, extruded, cast, blow molded, blown, profile extruded, spun, foamed or molded of any composition of the invention. The invention includes a use of any composition of the invention in any process of thermoforming, injection molding, extrusion, casting, blow molding, spinning, blowing, profile extrusion, foaming, compression molding or a combination thereof.
    • 本发明包括一种方法,其包括(a)形成包含至少一种聚烯烃的聚合物混合物,所述聚合物混合物已经使用单中心催化剂和至少交联量的至少一种聚(磺酰基叠氮化物)交联剂制备; (b)成型所得混合物; 和(c)将所得成形的混合物加热至至少交联剂的分解温度的温度。 步骤以任何顺序进行,并且可选地包括子步骤。 单中心催化剂优选为约束几何形状或茂金属催化剂,但可选地为不是传统的齐格勒 - 纳塔Ti / MgCl 2催化剂如钒催化剂的另一种过渡金属催化剂。 本发明还包括通过本发明的方法获得的所有组合物以及由这些组合物形成的所有制品。 制品优选是由本发明的任何组合物进行热成型,压塑,注射成型,挤出,铸造,吹塑,吹塑,型材挤出,纺丝,发泡或模制的。 本发明包括在热成型,注射成型,挤出,铸造,吹塑,纺丝,吹塑,型材挤出,发泡,压缩成型或其组合的任何方法中使用本发明的任何组合物。

    • A polyether NOP comprises at least two natural oil moieties separated by a molecular structure having at least about 19 ether groups or by a polyether molecular structure having an equivalent weight of at least about 480, said polyol referred to hereinafter as a polyether NOP. The polyether NOP is preferably prepared by a process comprising admixing at least one polyether initiator having an equivalent weight of at least about 480 or at least about 19 ether groups per active hydrogen group with at least one natural oil or derivative thereof under reaction conditions such that at least one polyether NOP is formed. The invention includes reaction products of the polyether NOP or combinations thereof, optionally and preferably in admixture with at least one other polyol which preferably includes at least one polyether polyol and at least one monomer reactive therewith, preferably at least one polyisocyanate to form a polyurethane, preferably in the form of a foam, especially a high resilience foam. The invention includes articles comprising at least one polyether NOP, at least one polymer thereof, or at least one foam thereof.
    • 聚醚NOP包含至少两个通过具有至少约19个醚基团的分子结构分开的天然油部分,或通过当量为至少约480的聚醚分子结构,所述多元醇在下文中称为聚醚NOP。 聚醚NOP优选通过包括在反应条件下将每个活性氢基团当量至少约480或至少约19个醚基团的至少一种聚醚引发剂与至少一种天然油或其衍生物混合的方法制备,使得 形成至少一种聚醚NOP。 本发明包括聚醚NOP或其组合的反应产物,任选和优选与至少一种其它多元醇混合,其中多元醇优选包括至少一种聚醚多元醇和至少一种与其反应的单体,优选至少一种多异氰酸酯以形成聚氨酯, 优选为泡沫形式,特别是高弹性泡沫。 本发明包括包含至少一种聚醚NOP,至少一种聚合物或其至少一种泡沫的制品。
