摘要： The present invention provides polylactic acid particles, which are formed in a continuous matrix phase from a polylactic acid resin and have a particle diameter of 1 to 100 µm. In a differential scanning calorimetry (DSC) curve of the polylactic acid particles, derived from the analysis by DSC using a temperature rise of 10 °C/min, a peak of the cold crystallization temperature (T cc ) is shown at a temperature between the glass transition temperature (T g ) and the melting point (T m ). The polylactic acid particles have an aspect ratio of more than or equal to 1.00 and less than 1.05 and a roundness of 0.95 to 1.00. The polylactic acid particles have a flow time of 20 to 30 seconds.

摘要： Provided are thermoplastic polymer particles having an aspect ratio of 1.00 or more and less than 1.05, and a roundness of 0.95 to 1.00. The thermoplastic polymer particles are formed from a thermoplastic polymer resin in a continuous matrix phase. The thermoplastic polymer particles show a peak cold crystallization temperature (T cc ) at a temperature between a glass transition temperature (T g ) and the melting point (T m ) in a differential scanning calorimetry (DSC) curve which is derived from temperature rise analysis at 10 °C/min by differential scanning calorimetry.

摘要： The present invention provides thermoplastic polyurethane particles, which are formed in a continuous matrix phase from a thermoplastic polyurethane resin and have a particle diameter of 200-500 µm. In a differential scanning calorimetry (DSC) curve of the thermoplastic polyurethane particles, derived from the analysis of a temperature rise of 10°C/min by DSC, a peak of the cold crystallization temperature (T cc ) is shown at a temperature between the glass transition temperature (T g ) and the melting point (T m ). The thermoplastic polyurethane particles have a compression degree of 10-20%.
