Abstract: A process for producing aliphatic polyester wherein a crystallized aliphatic polyester prepolymer formed from an aliphatic dihydric alcohol and an aliphatic dicarboxylic acid and having a weight-average molecular weight of 2,000 to 100,000 is caused to undergo solid-phase polymerization in the presence of a volatile catalyst to make an aliphatic polyester having a weight-average molecular weight of 50,000 to 1,000,000. This process is more efficient than any prior process calling for a complicated step for catalyst removal, since it enables the removal of the catalyst from the reaction system during and/or after solid-phase polymerization. The polyester is comparable in stability to any aliphatic polyester having any catalyst removed therefrom.

Abstract: A continuous process for forming multilayer circuit structures which includes applying and curing a film forming polymer onto the matte side of a copper foil. The opposite (shiny) side of the foil is optionally but preferably cleaned, and applied with a photoresist which is then optionally but preferably dried. The photoresist is exposed, and developed to remove the nonimage areas but leave the image areas. The foil under the removed nonimage area is then etched to form a copper pattern, and the remaining photoresist is optionally but preferably removed. The foil is then cut into sections, and then optionally but preferably punched with registration holes. The copper pattern is then optionally but preferably treated with a bond enhancing treatment, optionally but preferably inspected for defects, and laminated onto a substrate to form a multilayered circuit structure.
