摘要:
A resinous copolymer polyelectrolyte product is produced by a process for addition polymerization of reactants having from about 0.0005 to 0.0050 neutralization equivalents of ionizable monomer per gram. The aqueous reaction mixture for polymerization contains both a cosolvent in proportions low enough to avoid formation of a solution of the polyelectrolyte in the final aqueous medium and an ionizing agent sufficient to ionize at least about 0.0001 neutralization equivalent of said ionizable monomer. The polyelectrolyte has a mean weight average not substantially in excess of 100,000 molecular weight.
摘要:
A holder for a beverage container, typically a can or a bottle, to provide supplemental cooling to the beverage. The holder includes support ridges, pedestal, or other support means to support the bottom of the can or bottle above the holder bottom to create a space for an ice or an ice and water cooling medium. A sealing means between the holder and the beverage container permits the container and the holder to be tipped for drinking without spilling the ice or ice and water used to provide the cooling.

A holder for a beverage container, typically a beverage can or a beverage bottle, to provide supplemental cooling to the beverage. The holder includes one or more support ridges, a pedestal, or other beverage container support means to support the bottom of the can or bottle above the holder bottom to create a space for an ice or an ice and water cooling medium. A sealing means between the holder and the beverage container permits the beverage container and the holder to be tipped for drinking without spilling the ice or ice and water used to provide the cooling. Various sealing means include a removable seal subassembly, a single piece gasket that fits on the holder, a seal ring, and a stretch membrane.
摘要:
The powder coating composition of the present invention includes a low-temperature mixture of a powder (A) and a powder (B), in which at least the powder (A) includes an unsaturated polyester resin and a free radical initiator for initiating polymerization of unsaturated polyester resins in the powder coating composition and the powder (B) includes a polymerization promoter and methods for making the composition. The powder (B) may further include an unsaturated polyester. The powders (A) and (B) are physically mixed at temperatures below which the polymerization promoter would cause the free radical initiator to initiate polymerization of the powder coating composition. Subsequently, the physically mixed powder coating composition is applied to a substrate and cured, during which the polymerization promoter causes the free radical initiator to initiate the curing reaction.
