Reversible Addition-Fragmentation Chain Transfer
Abstract. The kinetic studies of RAFT polymerization of VC show a linear increase of the molecular weight with the monomer conversion and the lowest polydispersity (PDI) ever reported for poly (vinyl chloride) (PVC) synthesized with CLRP method (PDI ∼ 1.4). The resulting PVC was fully characterized using the matrix-assisted laser desorption

Aluminium polymers, such as poly-aluminium chloride that give rapid flocculation, efficient removal of organics and less alum under certain conditions, but at a higher cost. Activated silica is sometimes used as a flocculant together with alum as coagulant.
PDF Erosion and Sediment Control Guidelines for Land Disturbing
erosion refers to the uniform removal of soil in thin layers by the forces of raindrops and overland flow. Rill erosion is the removal of soil by runoff moving in concentrated flows. Velocity and turbulence of the flow increases in these concentrated flow paths, with the resultant energy detaching and transporting soil particles.
