    摘要： There are provided new elastomeric copolymers of about 15 to 45 mol %, preferably about 25 to 35 mol % trioxane, about 55 to 85 mol %, preferably about 65 to 75 mol % of 1,3-dioxolane, said mol percents based on the total of trioxane and 1,3-dioxolane, and about 0.005 to 0.15 wt. %, preferably about 0.05 to 0.12 wt. % of 1,4-butanediol diglycidyl ether or butadiene diepoxide as a bifunctional monomer, based on the total weight of copolymer. The elastomeric copolymers may be prepared by mixing said monomers in a substantially dry state and under an inert atmosphere with a cationic polymerization catalyst, e.g, p-nitrobenzenediazonium tetrafluoroborate. The elastomeric copolymers have a strong interaction with moldable, crystalline acetal polymers comprising at least 85 mol % of polymerized oxymethylene units and may be used as a blending agent with such crystalline acetal polymers or as a bonding agent to improve the adhesiveness of the crystalline acetal polymer to other materials.

    摘要： A polyacetal binder is removed from an extruded or injection molded ceramic green body in less than 25 hours by a variable heating rate schedule in which the heating rate is reduced when the temperature of the green body reaches the point at which isothermal degradation of the polyacetal binder can take place and wherein at least 80 wt. % of the binder can be removed. In air, the isothermal removal of the binder can take place within the range of 160.degree.-220.degree. C. while in nitrogen the range is from about 300.degree.-360.degree. C.

    摘要： A ceramic composition which can be extrusion or injection molded to ceramic greenbodies comprises a sinterable powder mixed within a polyacetal binder and further includes a dispersing aid comprising a polyester oligomer formed by self condensation of a hydroxy fatty acid in which the hydroxy group is attached to an internal carbon atom of the fatty acid. The dispersing aid also acts as a stabilizer for the polyacetal binder during compounding with the powder.

    摘要： A method is described herein for packaging a plurality of glass sheets by: (1) coating a top surface of each glass sheet with a removable top protective film; (2) coating a bottom surface of each glass sheet with a removable bottom protective film; and (3) stacking the coated glass sheets next to one another such that the top protective film of one glass sheet is adjacent to the bottom protective film of another glass sheet. The top protective film and/or bottom protective film on each glass sheet has embossed features (e.g., rough features) formed therein which make it easier to separate one glass sheet from one another glass sheet because of the presence of air pockets caused by the embossed features located between the stacked glass sheets. The coated glass sheet and a container that can store a plurality of the coated glass sheets are also described herein.
