    摘要： This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated hazing in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization or haze inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, the crystalline crosslinker resin visually appears to separate and recrystallize out of the molten powder less completely than it does in the absence of the recrystallization or haze inhibitor. This prevents a visible haze from developing on the surface of the coating upon curing with UV radiation.

    摘要翻译： 本发明提供一种UV固化粉末涂料组合物，其包含非结晶不饱和聚酯基础树脂，与基础树脂共可共聚的结晶不饱和交联剂树脂和光引发剂的颗粒混合物，其在固化涂层中显示出减少或消除的混浊 在由某些热敏基材所要求的低温下固化时由其形成。 这通过在粉末组合物中掺入由结晶环氧树脂组成的重结晶或雾度抑制剂来实现。 当该粉末混合物熔化以固化时，结晶交联剂树脂目前看起来比在不存在重结晶或雾度抑制剂的情况下更不完全地从熔融粉末中分离和重结晶。 这防止了在用UV辐射固化时在涂层的表面上发生可见的雾度。

    摘要： This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated hazing in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, all of the crystalline resin species tend to separate and recrystallize out of the molten powder slower and less completely than they do in the absence of the recrystallization inhibitor. This prevents a visible haze from quickly developing on the surface of the molten coating before the coating can be cured with UV radiation.

    摘要： A process for preparing a poly(arylene sulfide) and copolymer thereof from a poly(arylene sulfide disulfide) is provided which comprises contacting the poly(arylene sulfide disulfide) with a polyhalo-substituted cyclic compound having unsaturation between adjacent ring carbon atoms and having halogen atoms attached to the ring carbon atoms in a polar organic compound and a basic compound at an elevated temperature. Alternatively, the poly(arylene sulfide disulfide) can be substantially dissolved in the polar organic solvent at elevated temperature to form fragments which can be contacted with the polyhalo-substituted cyclic compound in a polar organic compound and a basic compound at an elevated temperature. The fragments also can be isolated, recovered and then contacted with the polyhalo-substituted cyclic compound in a polar organic compound and a basic compound at an elevated temperature.

    摘要： A confluent system includes an internal venturi; an open hopper in gaseous communication with the internal venturi, the open hopper being configured to receive solid large particles; and a fluid bed in gaseous communication with the internal venturi. The method includes a set of coatings and composite structures formed from a portion of the solid large particles applied to workpieces by gas-supported transfer then fused together by heating that comprise large-scale variations in structure provided by the inclusion of particles that are larger in at least one dimension than conventional powder coating particles.
