  In the process of the present invention, a solvent-soluble polyimide is produced by polycondensing at least one tetracarboxylic acid component with at least one diamine component in a solvent in the presence of a tertiary amine. The tetracarboxylic acid component is selected from the group consisting of tetracarboxylic dianhydrides represented by the following formula 1: 1 wherein R is as defined in the specification, and tetracarboxylic acids and their derivatives represented by the following formula 2: 2 wherein R and Y 1 to Y 4 are as defined in the specification. Unlike the conventional techniques using an excessively large amount of a chemical imidation agent such as acetic anhydride and a chemical imidation catalyst such as triethylamine, in the process of the present invention, the solvent-soluble polyimide having a high polymerization degree is easily produced in a solvent with good productivity by using only a catalytic amount of the tertiary amine.

  在本发明的过程中，通过在溶剂中与三级胺共存下，将至少一种四羧酸组分与至少一种二胺组分进行聚合缩合反应，制备出可溶于溶剂的聚酰亚胺。所述四羧酸组分选自以下化学式1所表示的四羧酸二酐：1其中R如规范中定义，以及以下化学式2所表示的四羧酸及其衍生物：2其中R和Y1至Y4如规范中定义。与传统技术使用过量的化学亚酰胺剂（如乙酸酐）和化学亚酰胺催化剂（如三乙胺）不同，在本发明的过程中，仅使用催化量的三级胺，即可在溶剂中高效地制备出高聚合度的可溶于溶剂的聚酰亚胺。

  The present invention provides a powder coating comprising associated particles having an average particle diameter of 3-70 µm, said associated particles containing fine polymer particles having an average particle diameter of 0.01-2 µm. The powder coating of the present invention comprises powder coating particles which have a relatively narrow particle size distribution, which have a relatively small average particle diameter, and which are controlled in shape. Moreover, the powder coating can be produced at a high yield, is greatly superior in fluidity and electrifiability as compared with conventional powder coatings; gives a coating film having excellent luster and sufficient smoothness; and can be applied in a thin film.
