    • Rapidly functional chemical fixing systems for anchoring elements, which fixing systems comprise a radically curing olefinic reactive resin formulation, a hardener and optionally additives, wherein the reactive resin formulation is composed of one or more curing olefinic reactive resins, one or more aminic accelerators, one or more non-phenolic (anaerobic) inhibitors and no or one or more phenolic inhibitors, and as the hardener there is provided a hardener with at least one peroxide as the initiator, wherein as the aminic accelerator(s) the reactive resin formulation comprises at least one highly active aminic accelerator in an amount of at least 1.5% by weight, based on the mass of the reactive resin formulation, the mass ratio of the accelerator to phenolic initiator is >5, and the reactive resin formulation comprises as non-phenolic inhibitor(s) up to 5% by weight of at least one non-phenolic inhibitor which has hardly any effect on the curing time, and in the hardener at least 1% of peroxide is provided. The very rapidly curing chemical fixing systems are especially suitable for fixing anchoring elements in the construction industry; these anchoring elements may become fixed a short time after the introduction of the chemical fixing system.

    • The present invention is concerned with the production and use of water-insoluble particulate heteropolymers made by sequential emulsion polymerization in dispersed particles of which a "core" of a polymeric acid is at least partially encased in a "sheath" polymer that is permeable to a volatile base, such as ammonia or an organic amine, adapted to cause swelling of the core by neutralization. The aqueous dispersion of the acid-containing core/sheath particles is useful in making water-base coating compositions wherein it may serve as an opacifying agent when a volatile base is used to at least partially (to a pH of at least 6) neutralize the heteropolymer, microvoids being formed in cores of the swollen particles in the film during the drying thereof. Thus, the heteropolymer dispersion can serve as an opacifying agent in coating compositions, such as water-base paints, as a supplement or replacement of part or all of the pigmentary material or extenders that would otherwise be used in such coating compositions.For convenience of description herein, the terms "core", "sheath", and "core/sheath polymr" are frequently used to refer to the distinct functional components of the individual polymer particles of the essential "mode" of the heteropolymers of the present invention even though in actuality, the components of the polymer particles thereof may not have the precise arrangement implied by this terminology.
    • 本发明涉及通过在其分散颗粒中顺序乳液聚合制备的水不溶性颗粒状杂聚物的制备和使用,其中聚合酸的“芯”至少部分地包封在可渗透的“护套”聚合物中 挥发性碱,例如氨或有机胺,适于通过中和引起芯的溶胀。 含酸芯/皮颗粒的含水分散体可用于制备水性涂料组合物,其中当使用挥发性碱至少部分(至少6的pH)时,其可以用作不透明剂,中和 杂聚物,在其干燥期间在膜中的溶胀颗粒的芯中形成微孔。 因此,杂聚聚物分散体可以用作涂料组合物中的遮光剂,例如水基涂料,作为另外将用于这种涂料组合物的部分或全部颜料材料或增量剂的补充或替代物。 为了方便本文的描述,术语“芯”,“护套”和“芯/鞘多聚体”经常用于指本发明的杂聚物的基本“模式”的各个聚合物颗粒的不同功能组分 即使实际上,其聚合物颗粒的组分可能不具有由该术语所暗示的精确布置。
