ANVENDELSE AF MODIFICEREDE ETHYLENOXIDADDITIONSPRODUKTER SOM SLIPMIDDEL VED FREMSTILLING AF TRANSPARENTE FILM, FOLIER ELLER PLADER AFPOLYURETHAN

摘要

In the manufacture of plastic articles, particularly thermoset plastic sheets having good optical properties, by a process which involves forming the article on a surface to which the article tends to adhere, numerous and important advantages are realized by using, as a release agent which facilitates removal of the article from the surface, a salt of an addition product of a lower alkylene oxide which can be prepared by the fixation of a lower alkylene oxide on an organic material having a group reactive therewith, such as, alcohols, acids and amides, and subjecting the resulting product to esterification and neutralization.
