The present invention concerns a method for forming a silane modified polyester composition. In addition, the invention concerns a silane modified polyester composition obtained by such method and use of such composition. In particular, the present invention concerns a method comprising subjecting polyester blend and polysiloxane mixture to react through reactive extrusion in a melt compounding process to form a silane modified polyester composition.

Techniques herein include methods of patterning a substrate using surface energy differences found in some fluorinated polymers or polymers with long chain alkyl functionality that promotes surface or top layer segregation in a bilayer polymer system to facilitate overburden removal when the polymer mixture is deposited over a relief pattern. The method allows for fast removal of the overburden to expose the anti-spacer region which, after acid diffusion and subsequent deprotection, is also soluble in a developer. Incorporating the highly developer-soluble polymer at the top of the top layer removes the need for the remaining polymer to have a specific dissolution rate in developer.

A compression moulding machine comprises: an extrusion unit configured to extrude a rod of pasty polymeric material; a cutting element, configured to portion the rod into individual charges; a rotary carousel, including a plurality of moulds, each mould being configured to receive a respective charge and to form a corresponding object from the charge; a feeder, configured to convey each charge to a respective mould at a feed position; an inspecting device, configured to capture inspection data, representing a composition of the rod or of the charges.

Tools for sealing a tubing in a downhole environment. The tools feature top and bottom slip assemblies and a monolithic sealing element. The monolithic sealing element includes a portion that is disposed between the top and bottom slip assemblies as well as portions that encapsulate the slip assemblies. When the tool is actuated from a run-in configuration to a set configuration, the slips move toward each other squeezing the sealing element so that it forms a fluid-tight seal with the tubing. Teeth of the slip assemblies penetrate the portions of the sealing element disposed thereon and bite into the tubing.

A method of manufacturing an oral dissolvable film that includes curing the slurry with ultraviolet radiation (UVR) and/or microwave radiation, alone or in combination with convection heat, to provide a cured film.

In one aspect, methods for forming three-dimensional articles are described. In some embodiments, a method described herein comprises providing a first mold, wherein the first mold comprises an interior volume, and injecting a first fluid material into the interior volume of the first mold. The method further comprises solidifying the injected first fluid material within the interior volume of the first mold to form a solidified object.
