摘要:
This invention discloses improved heterogeneous acid catalysts and a method for preparing these catalysts. A heterogeneous acid catalyst has been prepared by coating a carrier with an aqueous emulsion containing a fluorocarbonsulfonic acid polymer in the sulfonyl fluoride form, removing the excess water, heating to a temperature above the softening point of the polymer for a time, and then converting the polymer to the active sulfonic acid form. The substrate has pores of about 0.1 micrometers or greater and a surface area of about 20 m.sup.2 /g or less.

Disclosed are polyolefin copolymer films comprising alkoxysilane groups and a catalyst for cross-linking the alkoxysilane groups; wherein the cross-linking catalyst is a Lewis or Bronsted acid or base compound that has a relatively high melting point and therefore initiates the cross-linking essentially only at the lamination temperature, preferably at or above at least 50° C. Also disclosed are films wherein (i) the layer or layers comprising the alkoxysilane groups, including surface layer(s), comprise the cross-linking catalyst; or (ii) layer or layers comprising alkoxysilane groups do not contain cross-linking catalyst and have a facial surface in adhering contact with a layer of a thermoplastic polyolefin copolymer comprising the cross-linking catalyst; or (iii) there is a combination of layers (i) and (ii). Also disclosed are laminated glass structures and processes for their preparation that employ such films. The disclosed laminate structures include safety glass and photovoltaic modules.
摘要:
Laminated structures comprising a (i) glass layer, (ii) first alkoxysilane-containing polyolefin (PO) layer, (iii) catalyst layer, and (iv) second alkoxysilane-containing polyolefin layer, each layer having opposing facial surfaces, are prepared by a method comprising the steps of applying in adhering contact: A. One facial surface of the first PO layer to one facial surface of the glass layer; B. The catalyst layer to the facial surface of the first PO layer opposite the facial surface of the first PO layer in adhering contact with the glass layer; and C. The second PO layer to the facial surface of the catalyst layer opposite the facial surface of the catalyst layer in adhering contact with the first PO layer.
摘要:
The invention relates to functionalized interpolymers derived from base olefin interpolymers, which are prepared by polymerizing one or more monomers or mixtures of monomers, such as ethylene and one or more comonomers, to form an interpolymer products having unique physical properties. The functionalized olefin interpolymers contain two or more differing regions or segments (blocks), resulting in unique processing and physical properties.

A method of playing an object selection game (20), includes providing a set of objects containing a plurality of different individual objects, wherein each individual object has an order value in accordance with an ordering rule. A subset of the set of objects is dealt to a player in accordance with a dealing rule. A portion of the subset of objects is revealed to the player in accordance with a revealing rule. The player then selects any previously unselected object from the subset of objects in accordance with a selecting rule. After each selection, a terminating rule is used to test whether play shall stop, or whether additional objects are selected. The terminating rule stops play if objects are not selected in proper sequential order in accordance with the ordering rule. After play is stopped, a score is computed in accordance with a scoring rule. In preferred embodiments, the set of objects are playing cards, and a wager is placed on the outcome of the game.
摘要:
The invention disclosed herein is a method for preparing antimony trifluorodichloride whereby antimony trifluoride is dispersed in a liquid organic medium to form a slurry and contacted with chlorine. The invention further comprises a process for fluorinating a fluorinatable hydrocarbon or halocarbon whereby a fluorinatable hydrocarbon or halocarbon is contacted with the antimony trifluorodichloride prepared in the above process, and the fluorinated product is distilled off.
摘要:
Disclosure are films based on alkoxysilane-containing polyolefin resins with reduced melt strength, photovoltaic cell laminate structures and methods for their preparation. In the disclosed alkoxysilane-containing polyolefin resin films according to the invention, reduced melt strength is provided by, among other things, using optimized silane:initiator ratios and is shown to reduce detrimental film shrinkage and provide improved photovoltaic laminate structures.
