Title: Preparation of homo-, co- and terpolymers of substituted styrenes
Inventor: SHEEHAN MICHAEL T
IPC: G03F7/004
Filed: 2003-04-10
Abstract: A novel one-pot cost efficient process for the preparation of homo-, co- and terpolymers of p-hydroxystyrene or substituted p-hydroxystyrene and alkyl acrylates. The process involves polymerization of esters of p-hydroxystyrene (or its substituted analogs), alkyl acrylate monomers and/or one or more of ethylenically unsaturated monomers in an alcohol solvent in the presence of a free radical initiator. The reaction mixture containing the so formed polyme r is subjected to transesterification conditions using a catalytic amount of catalyst to result in co-and/or terpolymers of p-hydroxystyrene without cleavage of the alkyl ester in the acrylate repeat unit, and then removing t he catalyst from the system. Preferred embodiments include homopolymers of p- hydroxystyrene, copolymer of p-hydroxystyrene and tert-butyl acrylate and terpolymer of p-hydroxystyrene, tert-butyl acrylate and styrene. These polymers have a wide variety of applications including as photoresists in microelectronics industry.

Abstract: An automatic cup type beverage vending machine capable of mixing small pieces of ice and a liquid material finely and uniformly through the entire beverage. A liquid material (sugar and cream diluted with diluent hot water and a coffee solution) and small pieces of ice are agitated by an agitation mechanism and the cup is shaken by a shaking mechanism. Mixing of the liquid material and small pieces of ice can be performed not only by agitation of the liquid material and small pieces of ice but also by shaking of the cup. Therefore, the liquid material and small pieces of ice can be mixed uniformly and finely with each other in the entire beverage and any parts of them are not left in an insufficiently mixed state. The machine can therefore prepare a beverage which is not inferior in terms of touch to the tongue and palate and appearance to one prepared by mixing a liquid material and crushed ice while crushing ice by a mixer as in a beverage store.
