Abstract: Functionalized particles comprising a shell and a core and a payload that is embedded or entrapped, wherein the shell matrix is obtained by interfacial polymerisation of vinyltriethoxy silane and at least one other ethylenically unsaturated monomer copolymerizable with vinyltriethoxy silane, said functionalized particles being capable to chemically bind to a substrate, are suitable as controlled release systems for textile applications to impart durable softness and excellent water retention even after multiple laundries.

Abstract: The present invention discloses a single-step process for the formation of a three dimensional porous scaffold,the process comprising of carrying out ring opening polymerization of a monomer under high internal phase emulsion mode in the presence of at least one catalyst selected from methanesulfonic acid and stannous octoate to form a three dimensional porous scaffold. Further, the present invention discloses a three dimensional porous scaffold comprising of a polymer, to form a three dimensional porous scaffold having a pore size in the range of 0.1-30 micrometer and a porosity in the range of 75%-95%.
