Microemulsions of the water-in-oil type (w/o) capable of effecting ionic electric transfer and material interphase transfer, wherein the oily phase consists of a perfluoropolyether having perfluoroalkyl end groups or functional end groups of the hydrophilic type, said microemulsions being obtained by using perfluorinated surfactants, in particular having a perfluoroalkylpolyether structure, and/or...

Process for the preparation of vinyl chloride homo- and copolymers in powder form capable of yielding plastisols. A spray-drying operation is carried out on a vinyl chloride homo- or copolymer latex. The operation is carried out so that the processing temperature of the said latex to be subjected to the spray-drying operation is at least 40 DEG C and lower than the temperature of onset of deg...

The present invention relates to a method of manufacturing a fiber-reinforced plastics material. In this method, a foam of a binding agent containing powdery thermoplastic matrix is applied onto a reinforcing fiber web which is then dried, heated and pressed.

In order to produce the card body from a plastic material, the electronic module (14) whose covering (50) has an undercut (54), is placed in a mould (60,62). The module is held in place by suction (72). The plastic material is injected into the mould, thereby producing a moulding around the electronic module.
