Abstract: In an aspect, a composition comprises an alkali-swellable copolymer that is derived from a mixture comprising 15 to 50 wt % of an ethylenically unsaturated carboxylic acid; 30 to 70 wt % of an ethylenically unsaturated C1-2 alkyl carboxylate ester; and 15 to 40 wt of a nonionic ethylenically unsaturated surfactant monomer of the Formula (A); and less than or equal to 0.15 wt of a multifunctional monomer contains greater than 1 vinyl group. The composition has a pH of greater than or equal to 6. The composition can optionally comprise a surfactant.

Abstract: The present invention relates to the use of client and server software communicating with each other via the internet to create and maintain a multi-user role-playing game. The virtual world of the game is presented to each user by means of text and dimensional audio. The virtual world of the game is infinitely expandable and updateable, and the software reacts to user inputs to make the virtual world change according to user actions. New users may join an in-progress game at any time.
