Abstract： |
Preparation of highly cross-linked olefin polymer/calcium carbonate composite nano powders is carried out by: using lipophilic nano CaCO3 powders, olefin monomer and coupling agent as raw materials, and emulsion polymerizing them in water as dispersing medium with existence of emulsifier and initiator. Their weight percentage is as below: olefin monomer (54.5 - 97.8), CaCO3 powders (1 - 25), coupling agent (0.1 - 15), emulsifier (1 - 5), and initiator (0.1 - 0.5). The nano powders have CaCO3 as cores and organic olefin cross-linked net liked polymer as shells in spherical or elliptical ball with granular size distribution <100nm. |
