Neat PMP examples of lifetime h versus temperature C

The refractive index varies with the type of polymethylpentene, and can be, for example, about 1.463. [Pg.270]

These results relate to some grades only and cannot be generalized. [Pg.270]

The mechanical properties are generally fair, comparable to those of polypropylenes with slightly lower impact strength. Moduli and hardnesses are higher than those of polyethylene but rather weak, and notched impact strengths are much lower than those of polyethylenes. [Pg.270]

Shrinkage, coefficient of thermal expansion and creep are rather high. Absorption and alteration by moisture exposure are low. [Pg.270]

Thermoplastic neat polymethylpentenes have rather low moduli involving high strains for moderate loading. Consequently [Pg.270]
