Abstract: An aqueous composition comprises a filler and a dispersion of multi-stage polymer particles. The particles have a first stage formed from non-ionic ethylenically unsaturated monomers and ethylenically unsaturated acid functional monomers polymer and a second stage, formed from 85-98.5 weight % non-ionic ethylenically unsaturated monomers, 1-15 weight % of ethylenically unsaturated acid functional monomers, and either (i) 0.01-0.5 weight % a non-silane functional chain transfer agent and 0.4-2 weight % of an ethylenically unsaturated silane functional monomer or (ii) 0.01-0.5 weight % of a silane functional chain transfer agent and 0-2 weight % of an ethylenically unsaturated silane functional monomer based on total weight of monomers and chain transfer agent in the second stage. The weight ratio of the first stage to the second stage is 1:1 to 9:1. The weight ratio of filler to polymer particles is 0.01:1 to 2:1. The composition can form sealants that meet ASTM C920 class 50.

Abstract: A polymer with good compatibility comprising one or more non-ionic water soluble monomers, such as poly(ethylene glycol)(meth)acrylate (PEGMA), is provided that is suitable for use in aerosol hair styling formulations which have improved clarity. There is also provided a hair styling composition comprising (a) one or more fully soluble polymer, and (b) a solvent mixture, and optional other ingredients.

Abstract: Method and apparatus for the selective scaling, such as magnification and reduction, of video images stored as collections of image pels in a video memory. A lookup table is provided for determination of the values of the scaled image pels. A framing matrix of unscaled image pels is established for each scaled image pel. The framing matrix for the scaled image pels determines the outputs read out of the lookup table, and derivatively, determines the values of the scaled image pels. The scaled image pels are stored in the video memory for subsequent display or processing.
