摘要:
The present invention provides methods of making composite materials comprising combining particles of crosslinked rubber with one or more aqueous polymer dispersion of a suspension polymer to form a mixture in aqueous dispersion, and, optionally, subjecting the aqueous dispersion mixture to solid state shear pulverization to form materials that can be processed as thermoplastics at crosslinked rubber concentrations of from 10 to as high as 95 wt. %, based on the total solids of the material. The method may further comprise kneading and/or compression molding the pulverized product to form useful articles, such as roofing membranes and shoe soles.
摘要:
The present invention provides methods for making shapeable composite materials or shaped articles from recycled materials comprising forming a crumb slurry by, in any order, increasing the particle size of a composition comprising white water waste from one or more emulsion or dispersion polymer and combining the white water waste polymer with one or more waste thermoset material, preferably, ground tire rubber (GTR), and, then processing the combined material wet or dry as a thermoplastic to form the composite material or article. Additionally, shaped articles and composite materials can be made from substantially all recycled waste materials, such as white water waste from acrylic or vinyl polymer emulsions and waste rubber vulcanizates. The composite materials can consist essentially of reshapeable materials, i.e. without crosslinking agents, thermosettable compositions or compatibilizers to provide reshapeable or recyclable articles.

摘要:
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.

The present invention provides methods of making composite materials comprising combining particles of crosslinked rubber with coagulated aqueous polymer dispersions to form a mixture in aqueous dispersion, and subjecting the aqueous dispersion mixture to solid state shear pulverization to form materials that can be processed as thermoplastics at crosslinked rubber concentrations of from 10 to as high as 95 wt. %, based on the total solids of the material. The method may further comprise kneading the pulverized product to form useful articles, such as roofing membranes and shoe soles.
