PLA is harder than ABS, melts at a lower temperature (around  180Â°C to 220Â°C), and has a glass transition temperature between 60-65 Â°C, so is potentially a very useful material. It does exhibit higher friction than ABS however which can make it difficult to extrude and more susceptible to extruder jams.
Poly (acrylic acid) (PAA) is hygroscopic, brittle and colorless in nature with Tg at nearly 106 o C. At temperatures above 200 to 250 o C, it loses water and becomes an insoluble crosslinked polymer anhydride. synthesizing poly(N-isopropylacrylamid e)-block-PAA copolymer which responds to both temperature and pH stimuli 2. â¢ in preparing block copolymer of oligo (methyl methacrylate)/PAA for micellar delivery of hydrophobic drugs 3. â¢ as thickening agent for adhesives.
