The present invention concerns a biodegradable and compostable composition comprising i) 15-70% by weight of at least one biodegradable and/or decayable aromatic polyester; ii) 0-40% by weight of dolomite and/or calcium carbonate particles having a polished surface; iii) 0-30% by weight of starch of vegetable origin; iv) 1-5% by weight of at least one oil of vegetable origin; v) 5-30% by weight of an additive chosen from hydrated magnesium silicate such as talcum powder; vi) 0-50% by weight of at least one aliphatic polyester.

The disclosure discloses a high-frequency transmission LCP film and preparation method thereof. The preparation method comprises the following steps: (1) separately performing acetylation on monomers to obtain acetylated monomers; (2) performing high-temperature polymerization on the acetylated monomers, phenolic resin, acetic anhydride and zinc acetate, and performing pulverization to obtain liquid crystal copolyester; (3) ball milling the liquid crystal copolyester, an inorganic filler, a silane coupling agent and a glass fiber and mixing to obtain a mixture; and melt-plasticizing the mixture to form a film after cooling, performing longitudinal and transverse synchronous stretching, then winding and slitting the film to obtain a high-frequency transmission LCP film. In the disclosure, by adjusting the type and ratio of acetylated monomers and adding phenolic resin, a regular fibrous structure is obtained; and by adding an inorganic filler, a silane coupling agent and glass fibers, its mechanical properties are enhanced and dielectric loss is reduced, thereby obtaining an LCP film with low dielectric constant and low dielectric loss factor which can be applied to the fields of electronics, electricity, optical fiber, 5G communication and the like.

A process is disclosed for combining a cellulose ester polymer with a plasticizer. The cellulose ester polymer is in the form of particles and is combined with a wetting agent and the plasticizer while mixing. The wetting agent dramatically improves the ability of the cellulose ester particles and plasticizer to form a homogeneous mixture. During melt processing, in one embodiment, the wetting agent is volatilized and does not remain in the final product.
