A process for coating fresh eggs with a coating composition including coating the eggs with a polyethylene glycol-lactide aqueous dispersion, the process being useful for: reducing microbial content both within and outside the fresh eggs, preventing further contamination of the fresh eggs, extending the shelf life of the fresh eggs, maintaining the quality of the fresh eggs, and increasing the strength of the shells of the fresh eggs.

Provided is a polymer obtained by homopolymerizing a lactone monomer. The polymer contains a structural unit having a lactone ring containing three or more carbon atoms, wherein at least one of the carbon atoms, except for C of —C(═O)O—, of the lactone ring forms a part of a main chain; and wherein at least one of the carbon atoms, except for C of —C(═O)O—, which forms the lactone ring and is other than the carbon atom(s) forming a part of the main chain is bridged with an atom of the main chain.

A high-chi diblock copolymer (BCP) for self-assembly comprises a first block comprising repeat units of trimethylsilyl styrene (TMSS) and styrene, and a second block comprising an aliphatic carbonate repeat unit. The blocks are linked together by a fluorinated junction group L′ in which none of the fluorines of L′ are covalently bound to an atomic center of the polymer backbone. A top-coat free film layer comprising the BCP, which is disposed on an underlayer and in contact with an atmosphere, is capable of forming a perpendicularly oriented lamellar domain pattern on an underlayer that is preferential or non-preferential to the domains of the block copolymer. The domain pattern can be selectively etched to provide a relief pattern comprising a remaining domain. The relief pattern having good critical dimensional uniformity compared to an otherwise identical polymer lacking the silicon.

A bendable panel comprising a substrate layer, wherein the panel is provided with a mechanism enabling the panel to bend. The mechanism enabling the panel to bend is at least one groove or cut, and the depth of the groove or cut is no longer than the panel thickness. The substrate layer is prepared by the following materials with the following mass ratio: 100 parts of PVC resin or PVC powder, 30-55 parts of a styrene based elastomer, 150-300 parts of stone powder, sawdust or rock, 1-10 parts of an additive, and 1-4 parts of an elastomer coupling agent. The panel may be bent during the installation, and several panels can be seamlessly installed.
