An image construction computer game method is disclosed. Further disclosed are: a system for image construction formulated as a game; a system for performing the method; a computer-executable program stored on a non-transitory computer-readable storage medium, the program including the method; and an image processing apparatus that can record the method program in a storing section.

Image construction game

A precision fragmentation assemblage is disclosed, along with precision fragmentation assemblage catalysts derivable therefrom. A method for the preparation of a precision fragmentation assemblage is also disclosed, along with a method for preparing precision fragmentation assemblage catalysts from precision fragmentation assemblages. A method is further disclosed for using precision fragmentation catalysts in the polymerization of olefins to produce polyolefins.

Precision fragmentation assemblages and olefin polymerization catalysts made therefrom

A method of forming, by polymerization in an aqueous dispersion at pressures in excess of one atmosphere, a plurality of porous particles having at least one polymeric phase and at least one pore filling phase, wherein the pore filling phase includes a pore filler and a fugitive substance, is disclosed. Replacement of the fugitive substance with a replacement gas is further disclosed. Porous particles having a polymeric phase and pores containing a pore filler, and, optionally, a gaseous phase are also disclosed, as are their aqueous dispersions.

Porous particles, their aqueous dispersions, and method of preparation

Disclosed are a plurality of particles having a narrow particle size distribution, a processes for forming the same, and films containing the same. The plurality of particles, includes one or more discrete polymer shells, wherein at least one of the polymer shells is crosslinked with at least one monomer containing two or more double bonds polymerizable by free radical means; and a core material encased in the polymer shells, wherein the plurality of particles have a polydispersity of from 1.3 to 1.0.

Particles and a process for preparing the same

Disclosed are uniformly sized domains of liquid crystals, a method for forming the domains, and their performance in polymer dispersed liquid crystal displays. The method provides the ability to form discrete domains of liquid crystal surrounded by a polymer shell, also known as polymer encased liquid crystals, or PELCs. Further, the method provides for the ability to make PELCs that have uniformly sized particles. Displays made comprising uniformly sized PELCs demonstrate markedly improved electro-optical performance over displays made by conventional polymer dispersed liquid crystal processes.

Methyl methacrylate-butadiene-styrene polymer impact modifiers are improved by mixing them with about 0.01 to 5 percent by weight of a compound of the formula ##STR1## wherein R.sub.1 and R.sub.2 are C.sub.1 to C.sub.4 alkyl, R.sub.3 and R.sub.4 are H, C.sub.1 to C.sub.4 alkyl, or 4'-hydroxy-2'-R.sub.2 -5'-R.sub.1 -phenyl. Polyvinyl chloride (PVC) is mixed with the improved impact modifiers and has improved dispersion and resistance to discoloration.
