    • Polymeric particles comprising a polymeric matrix that has been formed from a blend of monomers comprising a first monomer which is an ethylenically unsaturated ionic monomer and a second monomer which is an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50° C., wherein secondary particles are distributed throughout the matrix, in which the secondary particles comprise a hydrophobic polymer that has been formed from an ethylenically unsaturated hydrophobic monomer which is capable of forming a homopolymer of glass transition temperature in excess of 50° C. and optionally other monomers, which hydrophobic polymer is different from the polymeric matrix. Also claimed is a process for preparing particles. The particles have improved shatter resistance. Preferably the polymeric particles comprise an active ingredient, especially a colourant. Such particles combine improved shatter resistance with the ability to retain the active ingredient. The particles of the invention can be used in a variety of industrial applications, for instance in the manufacture of inks, paper and cosmetics.
    • 包含聚合物基质的聚合物颗粒,该聚合物基质由包含第一单体(即烯键式不饱和离子单体)和第二单体(其是烯属不饱和疏水性单体)的单体共混物形成,所述第二单体是能够形成玻璃化转变温度过量的均聚物 其中二次颗粒分布在整个基质中,其中二次粒子包含由烯键式不饱和疏水单体形成的疏水性聚合物,该疏水性聚合物能够形成玻璃化转变温度超过50°的均聚物 和任选的其它单体,该疏水性聚合物不同于聚合物基质。 还要求的是制备颗粒的方法。 颗粒具有改善的抗碎裂性。 优选地,聚合物颗粒包含活性成分,特别是着色剂。 这种颗粒将改善的抗碎裂性与保留活性成分的能力相结合。 本发明的颗粒可用于各种工业应用中,例如用于制造油墨,纸和化妆品。
