| 摘 要： | 聚丙烯与其他聚烯烃共混改性，可明显提高熔体强度，采用40％CaCO3填充聚丙烯后用RA发泡剂发泡，可制得PP／Ca－CO3低发泡片材（密度为0．904g/cm^3）。该片材具有良好的可降解性，用于替代聚苯乙烯（PS）或纸浆制备一次性餐具，其力学性能可满足使用要求。

| Abstract: | The melt strength of the polymer is evidently improved in polypropylene(PP)/other polyolefins blends.For PP/CaCO-3 (40% filler content) composites containing RA,microcellular PP sheet was manufactured,with density of 0.904g/cm 3. This sort of sheet is biodegradable and is a substitute for PS or paper in making occasional cutlery with favorable mechanical properties that conform to user requirements. |
