[0260] Characterization of Diene Rubber Gels and Sealing Gels

[0261] Determination of conversion: The conversion of cold emulsion polymerization is calculated from the solids content of the latex solution. The determination of the solids in the latex was carried out by means of a Halogen Moisture Analyzer (Mettler Toledo, Halogen Moisture Analyzer HG63). For this purpose, aluminum pans (Mettler, item no. 13865) were inserted into the sample holder and tared. A HAF1 glass fiber filter (Mettler, item no. 214464) was then placed on top and the measurement started. Typically, fiberglass filters absorb about 0.5% of air humidity during storage. Subsequently, an aluminum dish with a dry glass fiber filter was inserted into the sample holder and the balance was tared. About 1 g to 1.5 g of latex was weighed and distributed over the largest area to enab...

Abstract

The present invention relates to: a sealing gel having a Mooney viscosity (ML1+4@100° C.) in the range from 100 MU to 170 MU, a sealing compound comprising the sealing gel of the invention, a method for producing such A method of a sealing compound, use of a sealing gel for improving viscoelastic properties in a sealing compound, and use of a sealing compound comprising a sealing gel for improving rolling resistance properties in a tire provided with a sealing layer.

Description

technical field [0001] The present invention relates to: [0002] A sealing gel with a Mooney viscosity (ML1+4)@100°C ranging from 100MU to 170MU, [0003] a sealing compound comprising the sealing gel according to the invention, [0004] ● a method for producing the sealing compound, [0005] the use of sealing gels in sealing compounds, and [0006] • Use of sealing compounds containing sealing gels in tires. Background technique [0007] In the operation of pneumatic tires for cars and trucks, there is a risk of damage to the tire as a result of the penetration of foreign objects and the tire being deflated due to damage. A flat tire often results in an unstable ride requiring immediate tire replacement or temporary repair to the tire. In order not to have to stop and leave the vehicle to change or repair a tire in hazardous traffic conditions, various tire and wheel designs have been developed. Therefore, there are tires on the market with a runflat characteristic,...
