Abstract： |
Preparation of highly cross-linked olefin polymer/silicon dioxide composite nano powders is carried out by: using inorganic nano SiO2 powders, oil-soluble olefin monomer and polyfunctional group 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: oil-soluble olefin monomer (58.5 - 98.8), SiO2 powders (0.5 - 17.5), oil-soluble polyfunctiional group coupling agent (0.1 - 17.5), emulsifier (0.5 - 5.9), and initiator (0.1 - 0.6). The nano powders have small size, higher content of non-extracted polymer, and uneasily taken-off coating. |
