Disclosed herein are an article and a method for preparing the article. The article comprises at least one layer A comprising fibers embedded in a composition comprising at least one vinyl ester resin; and a layer B comprising from 40 to 100% by weight relative to the total weight of said layer B of at least one thermoplastic polyester; from 0 to 60% by weight relative to the total weight of said layer B of a polyolefin composition; said composition comprising at least one polyolefin; and from 0 to 20% by weight relative to the total weight of said layer B of at least one additive selected from compatibilizing agent and/or impact modifier. Layer B may comprise a blow-molded layer, an injected-molded layer, an extruded-thermoformed layer, a sheet-extruded layer, a pipe-extruded layer, and an injection stretch blow-molded layer. Layer A may be in contact with layer B.

The present invention relates to rotomoulded articles and method for preparing said articles, said articles comprising: (i) at least one layer A comprising fibers embedded in a composition comprising at least one vinyl ester resin; and (ii) at least one layer B comprising: - from 40 to 100 %, preferably from 75 to 100 %, by weight relative to the total weight of said layer B of at least one thermoplastic polyester; - from 0 to 60 % by weight relative to the total weight of said layer B of a polyolefin composition; said composition comprising at least one polyolefin, preferably said at least one polyolefin is polyethylene;and - from 0 to 20 % by weight relative to the total weight of said layer B of at least one additive selected from compatibilizing agent and/or impact modifier; wherein at least one layer A is contacting one layer B.
摘要:
A rotomolded article may include at least one layer A containing fibers embedded in a polymer resin. The rotomolded article may include at least one layer B containing from 40 to 100 wt % of an aliphatic polyester. Such rotomolded articles may be prepared by applying to at least a part of an interior wall of a mold the at least one layer A, adding to the mold a composition for the at least one layer B, and rotating and heating the mold.
摘要:
The present invention relates to a rotomolded article, comprising at least one metallocene-catalyzed polyethylene resin comprising at least two metallocene-catalyzed polyethylene fractions A and B, wherein the polyethylene resin comprises: at least 25% to at most 55% by weight of polyethylene fraction A based on the total weight of the polyethylene resin, wherein fraction A has a melt index MI2 of at least 25.0 g/10 min as determined according to ISO 1133, condition D, at 190°C and under a load of 2.16 kg, and a density at least 0.005 g/cm 3 higher than the density of the polyethylene resin; and wherein the polyethylene resin has a density of at least 0.938 g/cm 3 to at most 0.950 g/cm 3 as measured according to ASTM D-1505 at 23°C; a melt index MI2 of at least 1.0 g/10 min to at most 25.0 g/10 min as determined according to ISO 1133, condition D, at 190°C and under a load of 2.16 kg. The present invention also relates to a process for preparing said rotomolded article.
