摘要:
A composition comprising particles which comprise a core material within a polymeric shell, wherein the core material comprises a hydrophobic substance, in which the amount of the polymeric shell forms at least 8% of the total weight of the particles, wherein the polymeric shell comprises a copolymer formed from a monomer blend which comprises, A) 5 to 90% by weight of an ethylenically unsaturated water soluble monomer, B) 5 to 90% by weight of a multifunctional monomer, and C) 0 to 55% by weight other monomer, and wherein the amount of the polymeric shell and the proportions of. A, B and C are such that the particles exhibit a half height of at least 350° C. The invention includes a process for the manufacture of particles and the use of particles in articles, such as fabrics, and coating compositions, especially for textiles.
