摘要:
A heat-expandable microsphere which comprises a shell comprising a thermoplastic resin and a blowing agent which is enclosed therein and has a boiling point not higher than the softening point of the thermoplastic resin, wherein the expansion ratio after maximum expansion is 50 or higher and the hollow microsphere obtained by heat expansion has durability in repeated compression of 75% or higher. Also provided is a process for producing heat-expandable microspheres which includes the steps of dispersing an oily mixture comprising a polymerizable ingredient and the blowing agent into an aqueous dispersion medium containing a specific water-soluble compound and polymerizing the polymerizable ingredient contained in the oily mixture.
摘要(中):
一种热膨胀性微球,其包含包含热塑性树脂的壳体和封入其中的沸点不高于热塑性树脂的软化点的发泡剂,其中最大膨胀后的膨胀率为50以上, 通过热膨胀获得的中空微球体在反复压缩中具有75%以上的耐久性。 还提供了一种生产热膨胀性微球的方法,其包括以下步骤:将包含可聚合成分和发泡剂的油性混合物分散到含有特定水溶性化合物的水性分散介质中并聚合含在油性混合物中的可聚合成分 。
