| abstract |
The invention refers to the field of chemistry and relates to a method, whereby the plastic surfaces have, for example, an improved adherence or anti-adherence. The aim of the invention is to specify an easily manageable method for activating or passivating the plastic surfaces. To this end, the invention provides a method for modifying plastic surfaces, according to which the plastic surfaces are modified during or immediately after a shaping process or are modified after a shaping process, and the temperature of the plastic surface is at least the onset temperature of the reaction peak in the DSC curve. In addition, one or more modifying substance(s) is/are entirely or partially brought into contact with the surface of the shaped plastics. Substances used as the modifying substance(s) are substances of the type that react with the surface of the shaped plastic and/or penetrate into the surface by interdiffusion and/or melt onto the surface. |
