  A process for preparing polymer non-aqueous dispersions to be formulated together with a binder component in coating compositions, which comprises the steps of: (1) emulsion polymerizing a hydroxy group containing α,β-ethylenically unsaturated monomer, a polyfunctional α,β-ethylenically unsaturated monomer and an α,β-ethylenically unsaturated monomer different therefrom by using a water-soluble polymerization initiator, preferably a persulphate, in a soap free system or in the presence of an ester group containing anionic or cationic surfactant; adding an organic solvent, preferably comprising an amphipathic organic solvent, to a resultant polymer aqueous dispersion; and then adding a basic compound catalyst when the anionic surfactant is used or an acidic compound catalyst when the cationic surfactant is used, to thereby hydrolyze completely said surfactant and water-soluble polymerization initiator at a temperature not exceeding 95°C as in the condition of suspension; (2) adding an acidic or basic compound to said suspension to neutralize said basic or acidic compound catalyst: then after adding dispersion stabilizing resin, further adding an amine salt of organic acid, followed by leaving said suspension to stand to separate into organic and water layers; and isolating the organic layer from the water layer; and (3) removing residual water in the organic layer. The resultant polymer non-­aqueous dispersion comprises polymer particles having a total ionic group concentration (I) less than 2x10⁻⁵ mol/g particle, a hexane tolerance (HT) from 5 to 40 exclusive and a degree of swelling in acetone (S) less than 10, and used with a binder component comprising a polyol resin and a curing agent for preparing coating compositions.

  A process for agglomerating rubber particles of a rubbery latex involves producing an agglomerating agent which is in the form of latex having particles which comprise high molecular weight polyoxyethylene bound therein. The agglomerating agent is admixed with an elastomeric latex to form agglomerated elastomeric particles. The process results in the formation of uniform size agglomerating particles, and utilizes a non-surfactant form of polyoxyethylene, which can be utilized in small amounts to yield the desired agglomerated elastomeric latex. The agglomerated particles may then be utilized as the substrate for graft copolymers, such as acrylonitrile-butadienestyrene graft copolymers.

  一种使橡胶胶乳的橡胶颗粒团聚的工艺包括生产一种团聚剂，该团聚剂呈胶乳状，其颗粒中包含高分子量聚氧乙烯。凝集剂与弹性胶乳混合，形成凝集的弹性颗粒。该工艺可形成大小均匀的团聚颗粒，并使用一种非表面活性剂形式的聚氧乙烯，只需少量使用即可产生所需的团聚弹性胶乳。然后，可将团聚颗粒用作接枝共聚物（如丙烯腈-丁二烯-苯乙烯接枝共聚物）的基质。
