Therefore the desiredpolymers of the dispersion are in a rubbery state if not crosslinked during the polymerization their Tg is below the polymerization temperature. However, UL assumes no responsibility or liability for the accuracy of the information contained on this website and strongly encourages that upon final product or material selection information is validated with the manufacturer.

Example 11 This example is similar to Example 10 above, instead using a non-carboxylated nitrile latex. Although the above particles are often seen the method of polymerization does not require their presence.

The technology to create broad or multimodal distributions is disclosed in European Patent Publication No. The information presented here was acquired by UL from the producer of the product or material or original information provider. The procedure is set forth below.

With our dispersions, resins and additives as well as technical expertise, we support customers in developing environmentally friendly, high performance adhesives. The starting latex adjusted to the appropriate pH e. The mineral oil, epoxy silane and mildewcide were then added and mixed until uniform.

These above listed monomers may optionally be present in the latex used as polymerization media. A preferred use is as an acrylate water-based caulking compound where the high solids and thixotropy of the dispersion allows for formation of a water-based caulk with low shrinkage.

A substantial portion of these monomers can be in the starting latex and still result in an acceptably low Tg for the latex copolymer. The nonionic and cationic emulsifiers are desirably used in lesser amounts such as less than 50 wt.

In the final dispersion of polymer particles, these particles from the latex willbe present probably in fewer number as one or more modes in the particle size distribution. With our dispersions, resins and additives as well as technical expertise, we support customers in developing environmentally friendly high performance adhesives. Another group is desirably from 0. If the monomers forming high Tg homopolymers e.

Commercially available carboxylated styrene-butadiene latex, carboxylated butadiene-acrylonitrilelatex, non-carboxylated butadiene-acrylonitrile latex, urethane latex, polyvinyl chloride copolymer, and poly vinylidene chloride copolymer latex are also used in the examples either as the only latex or in a A low speed, high torque electrically powered stirrer equipped with an anchor-type blade was used for agitation.

The resulting dispersions show bimodal or multimodal particle size distributions with particle diameters ranging from around 0. This example used the same latex and procedure as Example 12 and the sole monomer was n-lauryl methacrylate. The particle size distribution of the dispersion was typically trimodal with one mode centered at 0.

The pH of the latex media was adjusted to 6. Ut imperdiet finibus nulla, non varius turpis dignissim eu. The content of such third party sites is not within our control, and we cannot and will not take responsibility for the information or content.

A high solids polymer dispersion according to claim 3, wherein said latex is an acrylate latex, a urethane latex, a vinyl chloride copolymer latex, or a vinylidene chloride copolymer latex, or combinations thereof. Having only spherical particles appears to limit the polymer solids to less than 77 wt. These additives function to reduce polymer branching and molecular weight, which serves to prevent macromolecular gel formation during polymerization.
