摘要： An automated, on-line solvent elimination interface system is described for use in characterizing the Composition Distribution (CD) of unknown materials emerging from a fractionating unit (10) or a process stream. Fractionated samples to be analyzed, such as a polymer, in highly diluted form in one or more solvents, are provided by a fractionation unit (10) such as a gel permeation chromatograph (GPC), a high pressure liquid chromatograph (HPLC), or a field flow fractionator (FFF). A number of discharges of each particular fraction are supplied to individual collection units (20) within the interface system under controlled conditions of flow rate, temperature and pressure (vacuum) such that the solvents are flash-evaporated at the collection unit (20). A sufficient solid residue is built up on the collection unit (20) for analysis by, for example, a Fourier transform infrared (FTIR) analyzer.

摘要： An in-reactor polymer blend comprises (a) a propylene-containing first polymer; and (b) an ethylene-containing second polymer such that the polymer blend comprises between about 50 wt% and about 80 wt% units derived from ethylene and between about 50 wt% and about 20 wt% units derived from propylene. The blend is substantially free of dienes and the content of ethylene in the second polymer in the form of ethylene-ethylene-ethylene triads is at least 40%. The second polymer contains at least 0.1 branch having 8 or more carbon atoms per 10,000 carbons. In addition, the blend has a strain hardening index of at least 1.8, a shear thinning slope in the plot of log(dynamic viscosity) versus log(frequency) of less than -0.2 and exhibits at least two peaks when subjected to Differential Scanning Calorimetry (first melt) corresponding to a first melting point of at least 1500C and a second melting point of at least 400C such that the difference between the first and second melting temperatures is at least 200C.
