摘要： The present invention refers to a polymer composite that comprises sand preferably medium, at least a load, at least a resin selected from among dicyclopentadiene polyester resin (DCPD) and resin PET and at least a phase-compatibilizing additive and/or flexibilizing agent of the polymer structure. Further, the present invention refers to process of preparing said composite besides the use of said composite for preparing some articles including sleepers. This composite presents several advantages when compared to the materials used today for preparing sleepers as it is more versatile than steel, more available and as effective as wood, more durable than the concrete as it comprises an optimized composition that combines ideal physical-chemical properties to exercise the function for which it was intended.

摘要： A composition may contain a first polymer, a second polymer, and a block copolymer. The first polymer may be polylactic acid, starch, polybutylene succinate, poly(butylene adipate-co-terephthalate), or a mixture thereof. The second polymer may be polybutadiene, high impact polystyrene, or a mixture thereof. The block copolymer may be a block copolymer of polylactic acid and polybutadiene. The composition may be prepared by a process that includes contacting the first polymer with the second polymer and the block copolymer. Articles may be prepared from the composition.
