  • Publication number: 20080145626
    Abstract: Various embodiments of the present application relate to new form constructions and methods of forming and using the new form constructions. One method of printing a form construction involves (1) providing a substrate having a first major surface and a second major surface; (2) bossing at least a portion of the substrate to form a bossed substrate portion; and (3) attaching a signage to the bossed substrate portion. The signage or a printable portion of the substrate may then optionally be printed. An exemplary new form construction includes a substrate having a bossed substrate portion and an unbossed substrate portion; and a signage adjacent to the bossed substrate portion.

  • Patent number: 5897738
    Abstract: A process for preparing a sign that includes the steps of providing a sheet of material; defining on a surface of the sheet a series of image-bearig areas and non-image-bearing areas; treating the surface of the sheet with an essentially solvent-free composition comprising a colorant and a polymeric binder to selectively deposit the composition on the non-image-bearing areas of the surface of the sheet; and fusing the composition to create a continuous polymer film on the non-image-bearing areas.

  • Patent number: 4547603
    Abstract: Synthesis of methylcyclopentadiene with limited amounts of dimethylcyclopentadiene by-product. Cyclopentadiene monomer is complexed with metallic sodium in diglyme (diethylene glycol dimethylether) and reacted with an alkylating agent such as methyl chloride in the presence of a large stoichiometric excess of cyclopentadiene monomer. A high yield of methylcyclopentadiene is obtained with only a small production of undesirable methylcyclopentadiene. The excess cyclopentadiene is easily recycled in a continuous process.

  • Patent number: 4467106
    Abstract: A process for making polyether/polyester glycols and the products formed thereby. Polyether/polyester glycols having a molecular weight of about 200 to 2,200 are formed by heating any of various glycols at about 150.degree. to 250.degree. C. under carbon monoxide pressure in the presence of a halide promoter. Preferably, iodide or bromide and a transition metal-containing catalyst are used to produce polyether/polyester glycols having a molecular weight in the range of 900 to 1,200.

  • Patent number: 4456745
    Abstract: A process for the production of a polycarbonate glycol wherein a cyclic carbonate is catalyzed at elevated temperature by a cationic initiator. Compounds of structure (I) ##STR1## where R is alkylene, R' and R" are independently hydrogen, alkyl, alkaryl, aralkyl, or aryl, are heated at an elevated temperature in the presence of cationic initiators such as trimethyl aluminum to form a polymer. Production of a glycol product is assured by subsequent heating at about 200.degree.-220.degree. C. to form a polymer containing carbonate units of ##STR2## and having hydroxy end units bonded to a carbon not part of a carbonate function. The molecular weight of polycarbonate glycol is preferably at least about 1,000. Valuable new prepolymer mixes and polyurethanes may be prepared using the novel polycarbonate glycols of the invention.
