- Property
- LM-polymer has a self-emulsifying dispersibility, even with low hydrolyzed grade.
- LM-polymer can be dissolved in organic solvent, such as methanol, ethanol, acetone, Dimethyl sulfoxide.
( measurement condition : PVA concentration = 2%, churned state, 40 )
- LM-polymer is self-dispersible in cold water. No organic solvent, such as methanol, is needed to disperse LM-polymer.
- LM-polymer can be melt-molded on the temperature150
- 170 .
- In case of using as a secondary suspending agent for vinyl chloride polymerization, high porosity and an excellent absorptive property for plasticizer can be obtained with keeping bulk density.

- Storage
LM-polymer should be strictly kept away from wet areas and naked flame. Ingress of moisture may cause block formation.

- Dissolving method
LM-polymer should be slowly added into water at normal room temperature and sprinkled with fast stirring to avoid lump formation. After all the LM-polymer has been added, stirring speed should be reduced to prevent foaming. Keep agitation for about one and a half hours. The concentration recommended for a stock solution is 2 - 4 wt%. 2% solution is stable for about 3 weeks and 4% solution is about 2 weeks, at 20 .
