Abstract: A solid coating composition based on a polyolefin containing a filler is disclosed. The polyolefin is partly or completely reacted with either an unsaturated organic acid or an unsaturated organic acid anhydride.

Abstract: A process for the production of a wall for a package including producing a preform of the wall and stretching the preform of the wall where the preform includes a layer containing a polymer and having oxygen-scavenging properties. The preform and the stretching ratios applied are chosen (i) so that the time (t.sub.I) which the permeance of the wall for oxygen would take to rise to 1/5 of the value it would have in the absence of oxygen scavenging would be at least 10 days and (ii) if the preform were stretched at that time (t.sub.I) after the preform were produced, the time (t.sub.D) which the permeance of the wall for oxygen would take to rise 1/5 of the value it would have in the absence of scavenging would be at least 1/4 of the time (t.sub.I). The time between completion of step (A) and the commencement of step (B) is at least 10 days.

Abstract: The present invention is directed to a novel internal mold release agent for use in a polyurethane(urea) RIM process. The release agent broadly consists of the transesterification product of a fatty acid and a lower alkyl acetoacetate.
