The present invention relates to a method for the production of plastic footwear (10; 100) of the “full plastic” type by means of moulding using a polyurethane mixture (M; P). The method comprises the steps of: —providing a mould (20) having a mould cavity (22) defined by at least two impressions (28, 30) and designed to receive a shoe last (24) so as to define, when the mould (20) is closed, an interspace (26) having the shape and dimensions of the plastic footwear (10; 100) to be produced; —spraying a polyurethane mixture (M, P) onto said at least two impressions (28, 30) of the mould cavity (22); —inserting the shoe last (24) inside said mould cavity (22); —closing the mould cavity (22) so that the sprayed polyurethane mixture (M, P) occupies said interspace (26); —opening the mould (20), once at least the demoulding time (td) for the sprayed polyurethane mixture (M, P) has lapsed, such that the sprayed polyurethane mixture (M, P) has solidified inside the interspace (26) forming said plastic footwear (10, 100); —extracting the shoe last (24) from the mould cavity (22); —removing the plastic footwear (10, 100) from the shoe last (24).

The present invention is a unique process of manufacturing rigid members with precise “shape keeping” properties and with reflective properties pertaining to radio frequency energy, so that air, land, sea and space devices or vehicles may be constructed including parabolic reflectors formed without discrete permanent layering. Rather, such parabolic reflectors or similarly, vehicles, may be formed by homogeneous construction where discrete layering is absent, and where energy reflectivity or scattering characteristics are embedded within the homogeneous mixture of carbon nanotubes and associated graphite powders and epoxy, resins and hardeners. The mixture of carbon graphite nanofiber and carbon nanotubes generates higher electrode conductivity and magnetized attraction through molecular polarization. In effect, the rigid members may be tuned based on the application. The combination of these materials creates a unique matrix that is then set in a memory form at a specific temperature, and then applied to various materials through a series of multiple layers, resulting in unparalleled strength and durability.

A liquid crystal polyester resin comprising 42 to 80 mol % of structural unit (I) relative to 100 mol % of the total structural unit of the liquid crystal polyester resin, and ΔS (entropy of melting) defined by equation [1] is 0.01×10.sup.−3 to 2.7×10.sup.−3 J/g.Math.K:

ΔS(J/g.Math.K)=ΔHm(J/g)/Tm(K)  [1]

wherein Tm is an endothermic peak temperature determined by: after observation of an endothermic peak temperature (Tm.sub.1) observed when heating a liquid crystal polyester under temperature rising conditions of 20° C./minute from room temperature in differential scanning calorimetry, the liquid crystal polyester was maintained at a temperature of Tm.sub.1+20° C. for 5 minutes, followed by observation of the endothermic peak temperature observed when the temperature has fallen to room temperature under temperature falling conditions of 20° C./minute and then raised under temperature rising conditions of 20° C./minute, and ΔHm is an endothermic peak area of Tm:
