Abstract: A composition containing a semicrystalline poly(2,6-dimethyl-1,4-phenylene ether) having a glass transition temperature of 205 to 225° C. can be compression molded under conditions that include a molding temperature substantially below the glass transition temperature. In some cases, the crystallinity of the poly(2,6-dimethyl-1,4-phenylene ether) increases substantially during molding, even though the molding temperature is below the glass transition temperature. Also described are articles formed by the molding method, articles in which the poly(2,6-dimethyl-1,4-phenylene ether) has a crystallinity of at least 5 weight percent, and a method of increasing the crystallinity of poly(2,6-dimethyl-1,4-phenylene ether).

Abstract: The invention provides a multi-input multi-output (MIMO) control system comprising a controller adapted for receiving an input set of at least two control input parameters and a set of at least two control output parameters, said control system arranged for effecting a modified deadbeat control, in which said modified deadbeat control comprises a robust deadbeat control for an n-th order, linear time invariant (LTI) system based upon a series of cascade proportional integrating-differentiating (PID) controls, each PID control comprising a system transfer function having a nominator and a denominator, wherein for the nominator a constant gain (K) is selected for each PID control. The invention further provides a method for controlling a continuous process using this control system.

Abstract: A process for the production of a shaped object, including: (a) providing a mould including a cavity formed to produce an object of a desired shape; (b) heating the mould to a temperature of ≥145° C.; (c) supplying an ultra-high molecular weight polyethylene (UHMWPE) material into the mould; (d) closing the mould with a punch counterpart having such shape as to fit together with the mould cavity to form the shape of the desired object; (e) applying a compaction pressure through the punch to the material that is present in the mould, whilst maintaining the mould temperature, for such a compaction time that the material fuses to form the desired shape; (f) releasing the compaction pressure and removing the shaped object from the mould at a temperature of ≥145° C.; and (g) cooling the shaped object to a temperature of below the melting temperature of the UHMWPE material.
