| 英文名称 | Poly(acrylic acid) |
| 运输条件 | 常规运输 |
| 产品介绍 |
玻璃化温度106℃。商品有各种相对分子质量的品种，如数均分子质量130000、黏均分子质量450000、重均分子质量750000-4000000等。有刺激性。溶于水、甲醇、乙醇和二氧六环。Applications of PAA may include: · to study solute diffusion in Polyvinyl alcohol/PAA copolymer hydrogel · synthesizing poly(N-isopropylacrylamide)-block-PAA copolymer which responds to both temperature and pH stimuli · in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drμgs · as thickening agent for adhesives Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106oC. At temperatures above 200 to 250oC, it loses water and becomes an insoluble crosslinked polymer anhydride. Solubility of dried PAA in water increases with rise in temperatures. Concentrated solutions of PAA in water is thixotropic in nature. |
