Abstract:
The invention relates to a polyamide shaped part which can be obtained by anionic polymerization of a lactam containing microcapsules comprising a capsule core of latent heat-storage material and a polymer as the capsule wall. The invention also relates to a method for producing this shaped part and to its use in vehicle construction, for battery housings, for housings for small electronic units, and for systems for keeping food hot.
Abstract:
Pigment preparations in pellet form, which can be obtained by dry mixing of a solid pigment preparation (A) with a pellet disintegrating agent (B) and, if desired, one or more further auxiliaries from the group consisting of mould release agents (C), binders (D) and water-soluble surface-active additives (E) without particle comminution and subsequent compaction.
Abstract:
The present invention relates to microcapsules, comprising a capsule core and a capsule wall, wherein the capsule wall is composed of 50 to 90% by weight of one or more C1-C24-alkyl esters of acrylic and/or methacrylic acid (monomers I), 10 to 50% by weight of one or more polyvinyl monomers (monomers II), and 0 to 30% by weight of one or more monounsaturated, non-ionizable monomers (monomers III), which are different from monomers I, in each case relative to the total weight of the monomers. The invention further relates to a method for the production of said microcapsules, and to the use thereof in binding building materials, textiles and heat transfer fluids.
