Abstract
Poly(4-methyl-l-pentene) (PMP) is a linear α-polyolefin with isobutylbranches and with very interesting properties. From a practical point of view. PMP presents high optical transparency. relatively high thermal stability and chemical resistance. in addition to excellent dielectric characteristics and microwave transparency. Consequently. a wide range of applications is possible for this polymer. The chemical resistance. temperature stability. and transparency provide uses in medical equipment such as hypodermic syringes. blood collection and transfusion equipment. pacemaker parts. and respiration equipment; in chemical laboratory equipment such as cells for spectroscopic and optical analysis; and in wire and cable coating. Its microwave transparency grants applications in microwave oven cookware, food packaging, and service trays.
