Poly 1-butene (PB-1) has good applications in film

sheet

pipes

sealant and so on because of its outstanding properties such as creep resistance

heat resistance

grinding resistance

environment stress crack resistance.

therefore

it is honored as the "golden plastic"

However

compared with other polyolefin materials

the cost of PB-1 is higher and the crystalline transition rate is very slow. It need to let stand at room temperature for 7 ~10 days to complete from thermodynamic unstable crystal form Ⅱ crystal to thermodynamic stable crystal form I morphology transformation

this will increase the difficulty of processing. In recent years

researchers have been trying to make physical modification of PB-1 and have made some achievements in order to reduce the production cost of PB-1 and improve its performance. In this paper

the development progress of poly(1-butene) (PB-1) physical modification was introduced. The blending modification and filling modification are introduced

and the development prospect of PB-1 is prospected.
