Abstract:
A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.

Abstract:
The invention is concerned with the field of polymer chemistry and relates to elastomeric materials as usable, for example, as an inner liner material for motor vehicle tires, and to the use thereof. The problem addressed by the present invention consists in specifying elastomeric materials having relatively low gas permeability. The problem is solved by elastomeric materials comprising butyl and/or halobutyl rubbers or mixtures thereof, with 1 to 20 phr of at least one liquid imidazolium salt and with 1 to 40 phr of at least one filler having a graphitic structure. The problem is additionally solved by the use of the inventive elastomeric materials for elastomer materials having low to very low gas permeability.
