  公开号：EP0323719A2

  公开（公告）日：1989-07-12

  A process for producing pre-expanded particles of a thermoplastic resin, wherein said particles are of a polyolefin obtained by polymerizing an olefin in the presence of a Ziegler-Natta catalyst, and contain not more than 1% by weight of particles of diameter up to 105 µm and having a particle size distribution represented by:R(Dp) = 100exp[-(Dp/De)n] where Dp is300 or more and represents a particle diameter (µ m); R(Dp) represents a cumulative weight percentage; De represents an absolute size constant that is a particle diameter (µm) corresponding to R(Dp) 36.8% by weight; and n is 25 or more and is a distribution constant. The process can be carried out by dispersing the particles in a liquid medium (e.g. water) containing a blowing agent (e.g. an aliphatic hydrocarbon) and a phenolic antioxidant, heating to above the softening point of the polymer, and releasing the dispersion into a zone of lower pressure. Pre-expanded polyolefin particles free from scatters of cell diameter or particle diameter and having a high expansion ratio are obtained, which can be put into a mold for expansion molding to easily provide a uniformly expanded article.

  一种生产热塑性树脂预膨化颗粒的工艺，其中所述颗粒为在齐格勒-纳塔催化剂存在下通过聚合烯烃而获得的聚烯烃，且含有不超过 1%（按重量计）的颗粒，其直径不超过 105 µm，其粒度分布用以下公式表示：R(Dp) = 100exp[-(Dp/De)n]，其中 Dp 为 300 或以上，代表颗粒直径 (µ m)；R(Dp) 代表累积重量百分比；De 代表绝对粒度常数，即与 R(Dp) 36.8%（重量百分比）；n 为 25 或更多，是分布常数。 该工艺可通过将颗粒分散在含有发泡剂（如脂肪烃）和酚类抗氧化剂的液体介质（如水）中，加热至聚合物软化点以上，然后将分散体释放到压力较低的区域来实现。 得到的预膨化聚烯烃颗粒没有细胞直径或颗粒直径的散射，具有较高的膨化率，可将其放入模具中进行膨化成型，从而很容易得到膨化均匀的制品。
