Modified larch tannin was prepared by grafting copolymerization and sulfoalkylation, and successfully used as retanning agent, possessing good water solubility and enhanced penetration rate.
In this paper,using CCl4 as solventia,MMA reated with chloroperene rubber.A new graft chloroprene rubber adhesive which are low toxicity, high strength, stable store was synthetized.
The graffing rate and melt index of MAH g PE are investigated.It shows that CALA could decrease crosslinkage degree of the copolymer and improve the flowing property of the melt.
