Polyallomer

Name:
Polyallomer
Detailed information:
A copolymer that has a uniform crystalline structure but a mixed chemical composition. It is prepared by anionic coordination catalysis using a Ziegler catalyst. The best-known polyallomer is a copolymer of propylene and ethylene; it has the stereoregular crystalline structure of the homopolymers of these resins but a variable chemical composition. Temperature range −40 to 99C. The physical properties of polyallomers are generally intermediate between those of the homopolymers of the component resins but give a better balance of properties than blends of the homopolymers.

Use:

Vacuum-formed, injection-molded, blow-molded, and extruded products; film; sheeting; wire cables.
