A whitish rubber derived from the coagulated milky latex of the gutta-percha tree. 一种发白的橡胶,来自古塔树的凝乳胶。
The SEM analysis shows that the PCR particles are single continuous particles, which shows that the PCR particles are coagulated from the single polychloroprene rubber latex drops. SEM分析表明,采用逆凝聚包覆法制备的PCR粒子为单颗连续粒子,说明产物粒子是由单颗的胶乳液滴凝聚而成。
