Patent ID: 8658279

Claim:
Porous, free-flowing hydrophobic particles formed from a hydrophobic polymer, having a porosity of at least 30% by volume and an open pore structure, loaded with an aqueous fluid, said aqueous fluid comprising at least one compatibilizer additive of the formula (I) and being useful as an entraining agent for removal of volatile constituents from plastics, or for addition of auxiliaries in plastics, or said aqueous fluid optionally comprising a fertilizer, a plant-protection agent, or an insecticide, and/or growth-promoting agent, and being useful for soil improvement, for irrigation, for fertilization, and/or for plant protection, wherein R 1 is an alkyl moiety having from 1 to 6 carbon atoms, A and B, identical or different, are an alkyl moiety having from 1 to 6 carbon atoms or a group of the formula —Z—R 2 —R 3 , in which Z is a moiety of the formula —C 1 H 2r —O—, in which r is a whole number from 1 to 10, R 2 is a moiety of the formula —(C 2 H 4 O—) n (C 3 H 6 O—) m , in which m is 0 or a whole number from 1 to 4, n is a whole number from 1 to 12, and the arrangement of the units that are repeated n times and, respectively, m times are of block type or random, R 3 is an OH group or an alkyl moiety having from 1 to 6 carbon atoms, x is 0 or a whole number from 1 to 3, and y is 0 or a whole number from 1 to 3, where the compatibilizer additive always has at least one group of the formula —Z—R 2 —R 3 .
