Ethyl Cellulose K70 K100 for high molecular suspension polymerizaing
Inverse suspension polymerization: the aqueous solution of water-soluble monomer is suspended in the continuous phase as the dispersed phase, and the polymerization is carried out under the action of the initiator. Its application range is relatively small.
Suspension polymerization has the advantages: the heat of polymerization reaction is easily removed, the production operation is safe, the viscosity of the material does not change much during the reaction, and the temperature is easy to control. Different from emulsion polymerization, after the stirring is stopped, the generated polymer particles will automatically settle, which can be separated from water by centrifugation or filtration, and then dried to obtain commercial resin. The purity of the resin obtained by the suspension method is higher than that of the emulsion method.
【Introduction】
Name: Ethyl Cellulose
Abbreviation: EC
Structural formula:
In the formula , n stands for degree of polymerization and R for –H or –C2H5 .
Characteristics:
Ethyl Cellulose is a kind of white grains or powder, having no smell or tastes . Its 5% soliquoid shows neutral to litmus test paper . Its specific density 1 . 07~1 . 18 , heat distortion point: 135~155degree centigrade , and fire point: 330~360 degree centigrade . Ethyl Cellulose has good stability to light , heat , oxygen and wetness , and is stable to chemicals . It is resistant to alcali , dilute acid and salting liquid , soluble in some organic solvents , such as alcohol , ether, ketone , ester, aromatic hydrocarbon and halohydrocarbon , etc , and compatible to many celluloses , resin and nearly all plasticizers . Ethyl Cellulose has low combustibility, small hydroscopicity and good electric behavior . Its thin film and plastics have good mechanical strength and flexibility in a wide range of temperature .
