Colorless to pale yellow viscous liquids or elastic rubber-like semi-solids (soft gel for low molecular weight and toughness and elasticity for high molecular weight). Are odorless, odorless or slightly odor-specific. The average molecular weight is 200,000 to 87 million. Soluble in benzene and diobutene, can be mutually soluble with ethylene polyacetate, wax, etc., insoluble in water, alcohol and other polar solvents. Can make gum sugar at low temperature has excellent softness, at high temperature, there is a certain plasticity, to make up for polyethylene acetate cold too hard, hot and excessive softening when the mouth temperature and other shortcomings.

Good light resistance, heat resistance, antioxidant.
