摘要： The invention relates to a process for the manufacture of a shaped part of ultra high molecular weight polyethylene (UHMWPE) comprising melt processing, wherein a) the UHMWPE has a weight average molecular weight (Mw) of at least 1*106 g/mol, b) during the shaping the storage plateau modulus of the UHMWPE (G*) is kept at a value of at most 1.5 MPa, c) whereafter, before the cooling, the G* is raised to its final value. The invention further relates to a shaped part obtainable with the process and the use of the shaped part in a medical application.

摘要： A system for performing a chemical experiment comprises a reactor vessel having a wall defining a reaction chamber for receiving one or more fluids performing a chemical reaction. An analysis apparatus is located remote from said reactor vessel for analysing samples of said one or more fluids removed from said reaction chamber. Sampling means and transfer means are provided which are adapted for removing samples of said one or more fluids from said reaction chamber and transferring said samples to said analysis apparatus. The sampling and transfer means comprise a sample removal passage in communication with said reaction chamber and a sample transfer passage connected to said sample removal passage and extending to said analysis apparatus. The sample removal passage establishes an open communication between said reaction chamber and said sample transfer passage and the sample removal passage contains a flow restrictor. A pressure drop over said flow restrictor causes the removal of said samples from the reaction chamber.
