Abstract: The present invention provides a blend composition comprising a thermoplastic polyurethane and an acrylic acid copolymer wherein the thermoplastic polyurethane forms the discontinuous phase of the blend. The blend can be used in films or made into fibers for personal care products such as ostomy bags and diapers. Moreover, such materials are also useful for packaging products such as garbage bags.

Abstract: An in situ polymerized thermplastic resin incorporating hollow glass spheres, which are incorporated during polymerization of the resin, and a method of making a concentrate of hollow glass spheres dispersed in a thermoplastic resin with minimal sphere fracture by adding the spheres during polymerization of the resin.

Abstract: An improved moldable low density thermoplastic composite containing hollow glass spheres comprising a blend of thermoplastic resin, glass fiber reinforcement, and a concentrate of hollow glass spheres dispersed in thermoplastic resin.

Abstract: The invention relates to a method for producing glass, in which an oxide ss is mixed with a reducing agent and a combination of compounds which provide a dopant, donor-acceptor ion pair. This ion pair is selected from the group consisting of trivalent thulium plus trivalent cerium, trivalent bismuth plus trivalent europium, or trivalent bismuth plus trivalent samarium. The resulting mixture is homogenized and heated to about 1100.degree. C. The hot melt is allowed to fall on a ceramic surface and pressed with a second ceramic surface to produce a glass disk. When borax, phosphate, and germanate glasses are used, the glass ingredient is dried overnight at 150.degree. C followed by addition of a quantity of dopant ions, then homogenized, heated, and a disk formed as above.The glass thus produced is capable of emitting monochromatic radiation in predetermined regions of the spectrum wherein the emitted radiation has an unexpectedly high intensity compared with radiation emitted by singly doped glass.
