Synthesis and characterization of waterborne polyurethane modified by glucose
摘要
Abstract
Waterborne polyurethane ( WPU ) emulsion was synthesized by a prepolymer process using dimethylol propionic acid (DMPA) and glucose as hydrophilic agent and crosslinking agent,respectively. The structure of the films was confirmed by means of FTIR. The test results indicated that glucose was introduced into the main chain of polyurethane. TG analysis indicated that the thermal stability of WPU films modified with glucose was improved. The effect of glucose content on the mechanical properties of the WPU films was studied. The results showed that the properties of WPU films were improved with increasing weight of PG. When glucose content increased from 0 to 4.68％,elongation at break decreased from 529.9％ to 276.4％ and tensile strength increased from 10.9 MPa to 24.2 MPa.关键词
