  Expandable polylactic acid resin particles including (a) a base resin containing a polylactic acid resin having at least 50 mol % of lactic acid monomer component units, (b) a polyolefin wax in an amount of 0.0001 to 1 part by weight per 100 parts by weight of the base resin, and (c) a blowing agent in an amount of 1 to 30 % by weight based on the weight of the resin particles. The expandable resin particles can give expanded beads having an average cell diameter of 10 to 500 µm. The expanded beads can give in-mold foam moldings.

  New adhesives and methods for preparing them are disclosed that include polylactic acid irradiated with gamma radiation, such as by a Co60 source. Irradiation times are used that improve the characteristics of the adhesive materials. Generally, the dose of radiation is from about 5 kGy to about 200 kGy of gamma irradiation. The adhesives generally have melting temperatures in the range of at least about 140 to about 148° C. such that they can be conveniently used in conventional glue guns and other glue equipment. The disclosed adhesives can provide bond strengths in the range of about 1,600 psi or more to about 2,500 psi or more. The disclosed adhesives can include a crosslinking agents. They can be used to join a wide range of substrates including wood, metal, plastic, ceramic, glass or combinations of substrates. They can be conveniently prepared by heating a polylactic acid (polylactic acid) preparation and mixing the molten polylactic acid with one or more crosslinkers when present. The molten mixture can then be and the polylactic acid can be irradiated with the desired dose of gamma radiation. Irradiation can occur before during or after mixing with the crosslinking agent and before or after shaping into the desired shape or even after use to join substrates. The adhesives can be used to join substrates by any known method once heated to a molten state.

  本文公开了新型粘合剂及其制备方法，其中包括用伽马射线（如 Co60 源）辐照的聚乳酸。辐照时间可改善粘合剂材料的特性。一般来说，伽马辐照的剂量在 5 kGy 到 200 kGy 之间。粘合剂的熔化温度一般至少在约 140 至约 148 摄氏度之间，因此可方便地用于传统的胶枪和其他胶水设备。所公开的粘合剂可提供约 1,600 psi 或更高至约 2,500 psi 或更高的粘合强度。所公开的粘合剂可包括交联剂。它们可用于连接各种基材，包括木材、金属、塑料、陶瓷、玻璃或基材组合。可通过加热聚乳酸制剂并将熔融聚乳酸与一种或多种交联剂（如有）混合，方便地制备粘合剂。然后用所需剂量的伽马射线辐照熔融混合物和聚乳酸。辐照可发生在与交联剂混合之前或之后，以及成型为所需形状之前或之后，甚至在用于连接基材之后。粘合剂加热至熔融状态后，可采用任何已知方法连接基材。
