1.The Product is made of alkali-free glass fiber woven pipe coated with PVC resin through thermoplasticizing.
2.The swelling-sorption behavior of the cyclohexane and cyclohexene in AgCl/PMMA hybrid membrane was measured,and the result indicates that the sorption capacity of cyclohexene in the hybrid membrane was enlarged in comparison with pure PMMA membrane,but the sorption behavior of cyclohexane was less changed.
3.Polystyrene supporteo polyethylene glycol resin(PS-PEG-400 )with various PEG conten t was used as immobilized phase transfer catalyst for reactions of the addition of cyclohexenewith dichlorocarbene and N-butylation of acetanilide.
4.Using poly (4-merhylpentene-l) (PMP) as a membrane material and cyclohexane, irich-loroethylene, tetrachloroethylene, mixture of cyclohexane and trichloroethylene or tetrachloro-ethylene as solvents, the solution were cast to form homogeneous dense membranes, and the crystalline properties and surface morphology were investigated by DSC and TEM.
5.Using Poly(4-methylpentene-1) (PMP) as a membrane material, and cyclohexane, trichlo-roethylene, tetrachloroethylene, and the mixture of cyclohexane and trichloroethylene as solvents, these solutions were cast to form homogeneous dense membranes, and the membrane permeation behavious for oxygen, nitrogen, hydrogen, and carbon dioxide were investigated.
