摘要： Polyethylene having a relatively high specific gravity is modified to inhibit the production of static charges. A weak salt having properties of ionizing and having its positive ions bond chemically to the polyethylene is mixed in the polyethylene. A chemical agent is also dispersed in the polyethylene and is provided with properties of facilitating the dispersion of the positive ions of the weak salt throughout the polyethylene of high specific gravity for chemical bonding to the polyethylene. The weak salt may be cupric acetate and the chemical agent may be an amine. The amine is preferably ethoxylated. The material of this invention may be formed as non-transparent bags or as sheets. The material may be formed by mixing the different chemicals and extruding the mixture under conditions of controlled temperatures and pressures and for controlled dwell times.

摘要： A thermoplastic material formed from a hydrocarbon chain is modified to inhibit the production of static charges. The thermoplastic material may be a modified styrene or a polystyrene. A chemical agent is dispersed in the thermoplastic material and is provided with properties of combining with the carbon molecules in the modified styrene or the polystyrene. The chemical agent may be an amine. The amine is preferably ethoxylated.The polystyrene may be a crystal styrene or a high impact styrene. The amount of the ethoxylated amine in the material is dependent to some extent upon whether the polystyrene is a crystal styrene or a high impact styrene.The material of this invention may be formed as sheets as by extrusion or may be injection molded into different members such as panels. The material may be formed by mixing the ethoxylated amine and the polystyrene and extruding the mixture under conditions of controlled temperatures and pressures and for controlled dwell times.
摘要翻译：由烃链形成的热塑性材料被改性以抑制静电荷的产生。热塑性材料可以是改性苯乙烯或聚苯乙烯。化学试剂分散在热塑性材料中，具有与改性苯乙烯或聚苯乙烯中的碳分子结合的性质。化学试剂可以是胺。胺优选被乙氧基化。聚苯乙烯可以是结晶苯乙烯或高抗冲苯乙烯。材料中乙氧基化胺的量在某种程度上取决于聚苯乙烯是晶体苯乙烯还是高冲击苯乙烯。本发明的材料可以通过挤出形成为片材，或者可以注塑成不同的构件，例如面板。可以通过将乙氧基化胺和聚苯乙烯混合并在受控的温度和压力的条件下挤出混合物并且控制停留时间来形成材料。

摘要： A thermoplastic material formed from a hydrocarbon chain is modified to inhibit the production of static charges. The thermoplastic material may be a polypropylene. A weak salt having properties of ionizing and having its positive ions bond chemically to the thermoplastic material is mixed in the thermoplastic material. A chemical agent is also dispersed in the thermoplastic material and is provided with properties of facilitating the dispersion of the positive ions of the weak salt throughout the thermoplastic material for chemical bonding to the thermoplastic material. The chemical agent may also be bonded chemically to the thermoplastic material. The weak salt may be cupric acetate and the chemical agent may be an ethoxylated amine when the thermoplastic material is polypropylene. The polypropylene is preferably mixed with a suitable material such as polyethylene to enhance the amorphous characteristics of the thermoplastic material. The chemical bonding occurs primarily to the portion of the thermoplastic material having the amorphous characteristics.The material of this invention may be formed as bags or as sheets. The material may be formed by mixing the different chemicals and extruding the mixture under conditions of controlled temperatures and pressures and for controlled dwell times. Preferably the material is not vented to the atmosphere during the extrusion operation.
