    Abstract: Scaffold comprises a polymer defining macropores and comprising hydroxypropylcellulose partially substituted by a substituent comprising a self-crosslinkable group, which is crosslinked through the self-crosslinkable group. The macropores have an average pore size larger than 50 microns and are at least partially interconnected. In one method, bicontinuous emulsion comprising a continuous aqueous phase and a continuous polymer phase is formed. The polymer phase comprises hydroxypropylcellulose partially substituted by a substituent comprising a self-crosslinkable group, and is crosslinked through the self-crosslinkable group to form a polymer defining at least partially interconnected pores. In another method, phase separation is induced in a solution comprising a polymer precursor and water to form a bicontinuous emulsion comprising a continuous polymer phase and a continuous aqueous phase. The polymer precursor comprises a self-crosslinkable group and is crosslinked through the self-crosslinkable group in the emulsion to form a polymer defining at least partially interconnected macropores.

    Abstract: Biodegradable aliphatic polyester-based resin foamed particles that are excellent in environmental suitability and are produced using a source material derived from a plant, and a molded product of the same are provided. Thus, biodegradable aliphatic polyester-based resin foamed particles retaining high rigidity even when foamed at a high degree and having heat resistance, and a molded product are provided. Biodegradable aliphatic polyester-based resin foamed particles produced by foaming a resin composition obtained by melting and kneading a base resin constituted with a polymer (poly(3-hydroxyalkanoate)) having one or more recurring unit represented by the formula: [—O—CHR—CH2—CO—] (wherein, R is an alkyl group represented by CnH2n+1; and n is an integer of 1 to 15) and a polylactic acid-based resin, and an isocyanate compound. A molded product is produced by filling the resin foamed particles into a die, followed by heating and molding.
