    摘要： Polyurethane foams having improved retention of insulative properties can be prepared using one or more of two novel polyols. One of the polyols is a polyether prepared by reacting a monoepoxide with a compound having the general formula: ##STR1## wherein X is H, Li, Na, K; A is N, S or O; L is a covalent bond or a connecting group having from 1 to 10 carbons; M is any group capable of reacting with an ethylene oxide molecule in the presence of a basic catalyst; and J is an integer from 2 to 8. The other polyol is prepared by (1) admixing ethylene carbonate and one or more hydroxyl functional compounds under reaction conditions sufficient to react the ethylene carbonate and the hydroxyl functional compounds to produce a polyol precursor, and (2) admixing the polyol precursor with diethylene glycol and an anhydride, a dicarboxylic acid, a tricarboxylic acid or mixtures thereof, optionally in the presence of a catalyst.

    摘要： Succinic acid or succinic anhydride grafts of linear ethylene polymers are blended with other polymers or resins, e.g. polyesters and the like, to form blends having useful adhesive properties. The adhesive properties are useful in various laminates and in bicomponent fibers which comprise a core of a performance fiber, especially a polyester such as PET or PBT and polyamides, and a sheath of the grafted LDPE, HDPE or LDPE. The succinic acid or succinic anhydride groups are provided by grafting, respectively, maleic acid or maleic anhydride onto the LDPE, LLDPE, and HDPE, especially by a process wherein the grafting is done in a twin-screw, co-rotating extruder with the maleic acid or maleic anhydride being injected into a pressured zone of the extruder. The acid containing grafted polymer is dyeable in contradistinction to ungrafted polymer.

    摘要： Maleic anhydride can be satisfactorily grafted to polymers at low pressures by feeding the polymer through a multiple screw extruder and injecting the maleic anhydride and a free radical initiator into the extruder. The maleic anhydride and initiator can be pre-mixed in a solvent solution. The solvent and unreacted maleic anhydride can be removed by low pressure devolatilization. The graft copolymer has a yellowness index as measured by ASTM D-1925-70 less than about 10.0 and as measured by ASTM E-313-73 less than about 11.0. Further, between 0.75 and 2.0 weight percent of the graft copolymer comprises maleic anhydride. The graft copolymer can further be blended with an olefinic polymer to yield adhesive thermoplastics suitable for use as food packaging multilayer coextruded films.

    摘要： A novel microporous isocyanate-based xerogel composition is disclosed. The composition can be prepared by a method comprising (1) (1) admixing (a) a polyisocyanate component, (b) a substantially unreactive solvent, and, optionally, (c) a polymerization catalyst, water, an active-hydrogen compound or a mixture thereof, provided that (c) is included wherein (b) does not also function to catalyze polymerization; under reaction conditions sufficient to form a gel; and (2) removing the solvent under non-supercritical conditions sufficient to form a microporous xerogel composition. The compositions can be readily evacuated for use in thermal insulative applications such as vacuum panels, for uses such as appliance insulation, which show superior K-factor values when compared with, for example, conventional rigid polyurethane open-cell foams as used in similar applications.

    摘要： A method is disclosed for making thermoplastic bicomponent fibers by contacting under thermally bonding conditions (a) a first component being at least one high performance thermoplastic polymer, such as PET, PBT, nylon or the like, and (b) a second component which is olefinic and which forms at least a portion of the fiber's surface characterized by (b) including at least one grafted olefinic polymer, preferably at least one grafted linear ethylene polymer, having pendant succinic acid or succinic anhydride groups; whereby the fiber is dyeable. The bicomponent fibers made by this process can be in a variety of shapes (e.g., round, oval, trilobal, flat, or hollow) and configurations (e.g., symmetrical sheath/core or side-by-side or asymmetrical crescent/moon). The succinic acid or succinic anhydride groups are provided by grafting, respectively, maleic acid or maleic anhydride onto the linear ethylene polymers especially by a process wherein the grafting is done in a twin-screw, co-rotating extruder with the maleic acid or maleic anhydride being injected into a pressured zone of the extruder. The acid containing grafted linear ethylene polymer or polymer blends are dyeable in contradistinction to ungrafted linear ethylene polymers.
