Abstract

contas expandidas de resina poliláctiva e artigo moldado das contas expandidas. a presente invenção refere-se ao fornecimento de contas expandidas de resina poliláctica que são adequadas para serem modeladas em um molde. as contas expandidas podem formar de forma estável artigos moldáveis, em que as contas apresentam excelente ligação por fusão uma com a outra independentemente da forma do artigo moldado. contas expandidas que compreendem uma resina poliláctica à base de ácido como resina base, caracterizada pelas reações satisfatórias (1) e (2): (br:endo) > 25 ...(1) (brc:endo) > (brs:endo) <242> 0 ... (2), [em que (br: endo) é a quantidade de calor [j/g] que é absorvida pela conta inteira; (br:endo) é a quantidade de calor [j/g] que é absorvida pela superfície da conta; e (brc: endo) é a quantidade de calor em [j/g] que é absorvida pelo núcleo da conta, cada uma sendo determinada sob condições específicas [1] de acorodo com o fluxo de calor da calorimetria de varredura diferencial estipulada em jis k7122 (1987)].
