    • 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.
    • 由烃链形成的热塑性材料被改性以抑制静电荷的产生。 热塑性材料可以是聚丙烯。 在热塑性材料中混合具有离子化性质并使其正离子与热塑性材料化学键合的弱盐。 化学试剂也分散在热塑性材料中并且具有促进弱盐的正离子在整个热塑性材料中分散以使化学键合到热塑性材料的性质。 化学试剂也可以与热塑性材料化学键合。 弱盐可以是醋酸铜,当热塑性材料是聚丙烯时,化学试剂可以是乙氧基化胺。 聚丙烯优选与合适的材料如聚乙烯混合以增强热塑性材料的无定形特性。 化学键主要发生在具有无定形特性的热塑性材料的部分上。 本发明的材料可以形成为袋子或片材。 可以通过混合不同的化学品并在受控的温度和压力的条件下挤出混合物并控制停留时间来形成材料。 优选地,在挤压操作期间,材料不会排放到大气中。

    • Powder coating compositions are disclosed which comprise a blend of coreactable, thermosettable copolymers each of which have at least two different functional groups. Ordinarily, these polymers will be qualitatively difunctional, although they may contain more than two different functional groups, and quantitatively polyfunctional. At least one of the copolymers has epoxy functionality as one of its two or more different functionalities. Thus, in the preferred embodiments, the first copolymer of the blend has epoxy functionality and a second functionality selected from amide functionality, anhydride functionality and hydroxy functionality and is crosslinkable with the second copolymer through at least two different types of functional groups on the first copolymer. The second copolymer also is crosslinkable with the first copolymer through at least two different types of functional groups on the second copolymer and may be (a) anhydride functional and carboxy functional, (b) carboxy functional and amide functional, (c) carboxy functional and hydroxy functional, (d) epoxy functional and amide functional or (e) epoxy functional and anhydride functional. The second copolymer is advantageously employed in an amount such that its functionality of greatest concentration provides about 0.3 to about 1.2 functional groups per functional group on the first copolymer and the functionality of lesser concentration provides about 0.1 to about 0.4 functional groups per functional group on the first copolymer.
    • 公开了粉末涂料组合物,其包含可共混的,可热固化的共聚物的共混物,其各自具有至少两个不同的官能团。 通常,这些聚合物将是定性双官能的,尽管它们可以含有多于两个不同的官能团,并且定量地是多官能的。 共聚物中的至少一种具有作为其两个或多个不同官能团之一的环氧官能团。 因此,在优选实施方案中,共混物的第一共聚物具有环氧官能度和选自酰胺官能度,酸酐官能度和羟基官能度的第二官能度,并且可通过第一共聚物上的至少两种不同类型的官能团与第二共聚物交联 。 第二共聚物还可以通过第二共聚物上的至少两种不同类型的官能团与第一共聚物交联,并且可以是(a)酐官能团和羧基官能团,(b)羧基官能和酰胺官能团,(c)羧基官能团和 羟基官能团,(d)环氧官能团和酰胺官能团或(e)环氧官能团和酸酐官能团。 第二共聚物有利地使用的量使得其最大浓度的官能度为第一共聚物上的每个官能团提供约0.3至约1.2个官能团,并且较低浓度的官能团在每个官能团上提供约0.1至约0.4个官能团 第一共聚物。
