化学的特性

Poly(ethylene terephthalate) is a colourless rigid substance. Because of its structural regularity, the polymer readily crystallizes and the physical properties of the bulk material are greatly affected by the extent of crystallinity, which, in turn, is largely determined by the previous history of the material. In the production of fibre, the molten polymer is extruded through spinnerets into air at normal temperature. The filaments are thus rapidly cooled and are largely amorphous and are weak. The filaments are then drawn at a temperature above the glass-transition temperature (80°C), whereby molecular orientation and crystallinity are induced. Finally, the filaments are heated at about 200°C under tension to give a dimensionally-stable material of maximum crystallinity. The manufacture of poly(ethylene terephthalate) film closely resembles that of fibre and also involves extrusion, orientation and stabilization.

使用

Poly(butylene terephthalate) is used as an engineering material in a variety of applications which include automotive parts, electrical components and domestic appliance assemblies.

製造方法

It is prepared from 1,4-butanediol and terephthalic acid or dimethylterephthalate by processes which are essentially the same as those used for poly(ethylene terephthalate) and described in the preceding section. Due to the longer sequence of methylene groups, the polymer chains are more flexible and less polar than in poly(ethylene terephthalate). This results in a lower crystalline melting point (225°C) and glass-transition point (22-43°C). The low glass-transition temperature facilitates rapid crystallization in the mould and most poly(butylene terephthalate) is processed by injection moulding.

工業用途

Polyethylene terephthalate is a useful materialthat has good resistance to acids and alkalisprovided that they are diluted. It is insoluble inmany common solvents, although it does dissolvein aromatic and chlorinated hydrocarbons,especially when warm. It softens above250°C.
