    摘要： This invention comprises a film useful as an adhesive, a composition useful to make the film, and a laminate comprising the film contiguous with at least one metal substrate, at least one foam substrate or combination thereof. The composition comprises (a) at least one anhydride grafted olefin polymer, (b) at least one high density polyethylene, and (c) at least one elastomer which preferably has a tensile elongation at break of at least about 585%, a density of at most about 0.900 g/cm3 or a combination thereof. The anhydride grafted olefin polymer or combination thereof is preferably present in an amount of from about 20 to about 40 weight percent, the high density polyethylene or combination thereof is preferably present in an amount of from about 40 to about 60 weight percent, and the elastomer or combination thereof is preferably present in an amount of from about 17 to about 30 weight percent. Each anhydride grafted olefin polymer is independently most preferably a maleic anhydride grafted high density polyethylene. The high density polyethylene preferably has a melt index at most about 30 dg/min. The elastomer is preferably a substantially linear ethylene polymer or olefin block copolymer.

    摘要： The invention includes a multilayer film having at least 2 layers: (A) an adhesive layer comprising at least 40 weight percent of an ethylene/alkyl acrylate copolymer having a Vicat point (ASTM D 1525) of no more than 40 centigrade (° C.), at least 1 and at most 10 weight percent of an ethylene/alpha, beta-ethylenically unsaturated carboxylic acid copolymer, and at least 20 weight percent of a low density polyethylene, and 0 to at most 7 weight percent filler, hereinafter referred to as composition A; and (C) a barrier layer comprising at least 90 weight percent high density polyethylene, hereinafter referred to as composition C, in each layer, the percentages being based upon combined weight of polymers and filler and selected to total 100 percent by weight. Preferably the film further comprises at least one layer (B) a core layer comprising at least 20 weight percent linear low density polyethylene (LLDPE), at least 20 weight percent low density polyethylene different from LLDPE, at least 10 weight percent high density polyethylene and 0 to at most 5 weight percent filler, hereinafter referred to as composition B, the percentages being based upon combined weight of polymers and filler and selected to total 100 percent by weight. Such a film is useful to protect surfaces and preferably adheres when needed for protection and is removable after protection is no longer desired. Preferably, the film curls to an extent sufficient to help protect the edges of the protected surface.

    摘要： The specification discloses a method and apparatus for determining the gel time of thermoset resins by using a disposable vial, a disposable spindle for insertion into the vial, a locking collar releasably secured to the disposable vial for mounting the vial in a permanent sample cup and holding it against rotation with respect thereto, and a spindle adaptor releasably receiving the disposable spindle for mounting same to the spindle mount of a conventional viscometer. The thermoset resin is located in the disposable vial along with the disposable spindle. The permanent sample cup including the disposable vial and its contents is located in a heater and the spindle adaptor is secured to the spindle mount of the viscometer. The viscometer is operated and the gel time is determined as the length of time it takes until the viscosity of the heated resin sample begins to increase sharply.
