Abstract
The invention relates to a polymer composition with a polyester basis with a filler constituted by mineral or organic artificial fibers and inert finely grounded material, and to the process for its preparation. The product of the invention is also disclosed which is useful for the covering of both outdoor or indoor surfaces. The obtained material maintains a sufficient flexibility so that it can be coiled on small cored bobbins thus saving storage space. Several examples of the resin composition and curing methods are given.
