    Abstract: Fluoroelastomer compositions comprising fluoroelastomers having copolymerized units of a nitrile group-containing cure site monomer are cured with certain hydroxylamine derivatives. The hydroxylamine derivative is of formula R1(C(O))nNHOR2 wherein n is 0 or 1; R1 is H, C(O)R3, C(O)R4, C(O)OR3, or C(O)SR3; R2 is H, C(O)R3, or C(O)OR3; R3 is C1-C20 alkyl group, aryl, heterocycle, benzyl, 9-fluorenylmethyl, or CH2R4; and R4 is a fluoroalkyl group, with the proviso that R1 and R2 cannot simultaneously be H.

    Abstract: A method is provided for cleaning the interior of polymer processing equipment having a resin composition retained therein, wherein a contaminant material is adhered to at least a portion of the interior surface of the polymer processing equipment. The method comprises the steps of: charging the polymer processing equipment having a residual polymer composition retained in the interior thereof with a purging composition comprising 45-94 weight % of starch; 0.05 to 20 weight % of water; and (3) 5 to 45 weight % of polyol plasticizer, wherein the weight percentages of starch, water and polyol plasticizer are based on the total weight of starch, water and polyol plasticizer; operating the polymer processing equipment to i) convey the purging composition through the polymer processing equipment, thereby removing and withdrawing substantially all of the residual polymer composition from the polymer processing equipment and causing a portion of the purging composition to be retained as a residual purging composition within the interior of the polymer processing equipment; and ii) remove at least a portion of the contaminant material that is adhered to an interior surface of the polymer processing equipment; and removing the portion of the purging composition retained as a residual purging composition from within the interior of the polymer processing equipment.

    Abstract translation: 提供了一种用于清洗其中保留有树脂组合物的聚合物加工设备的内部的方法，其中污染物质粘附到聚合物加工设备的内表面的至少一部分上。 该方法包括以下步骤：将含有残留聚合物组合物的聚合物加工设备装入含有45-94重量％淀粉的清洗组合物; 0.05至20重量％的水; 和（3）5至45重量％的多元醇增塑剂，其中淀粉，水和多元醇增塑剂的重量百分比基于淀粉，水和多元醇增塑剂的总重量; 操作聚合物加工设备以i）通过聚合物加工设备输送清洗组合物，从而从聚合物加工设备中除去和排出基本上所有的残余聚合物组合物，并使一部分清洗组合物作为残余吹扫组合物保留 在聚合物加工设备的内部; 以及ii）去除粘附到聚合物加工设备的内表面上的至少一部分污染物质; 以及从所述聚合物加工设备的内部除去作为残余吹扫组合物保留的所述清洗组合物的部分。
