    Abstract: Disclosed is a spectroscopic probe apparatus useful for Raman, near infrared, luminescence, ultraviolet or visible spectroscopies that is formed with a robust method of construction using a molten metal soldering technique. The disclosed method and apparatus provides an optical probe that is easy to manufacture yet able to withstand drastic environmental conditions without damage and produce useful spectroscopic results under such conditions. In a preferred embodiment of the present invention, optical probe (100) comprises a housing (101), closed at one end by tip (102). Two optical fibers (103 and 104), one serving as an excitation channel for radiation from a source to a composition to be analyzed, the other comprising a collection channel for transmitting radiation from the irradiated composition to remotely situated detector means, extend from the terminal surface (105) of the tip through the length of the housing. On the terminal surface (105) of tip (102) is formed a cavity (106), which is filled with molten metal solder that solidifies on cooling to a solder plug. This plug comprises means for securing and sealing the ends of the optical fibre at the terminal surface of the probe tip.

    Abstract: Disclosed are branched polyester compositions having an I.V. of at least about 0.7 dl/g and a melt viscosity sufficiently high to permit foaming during extrusion or molding operations. These branched polyesters are readily foamable with a wide range of foaming agents to provide low density shaped articles, films and sheets. The branched polyesters comprise about 80 to about 99.9 wt.% of a polyester and about 0.1 to about 20 wt.% of an ethylene copolymer containing repeat units of ethylene and of a monomer selected from the group comprising acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate and vinyl alcohol. The polyester comprises repeat units from about 75 to 100 mol % of a dibasic acid having from 6 to 40 carbon atoms and 0 to about 25 mol % of a modifying dibasic acid and repeat units from about 75 to 100 mol % of a glycol having from 2 to 10 carbon atoms, 0 to about 25 mol % of a modifying glycol and 0 to about 25 mol % of a modifying compound selected from the group comprising amino alcohols, diamines and lactams.
