英文摘要 | 2-Methyl-1,5Penta-Methylene diamine(MPMD) is a methyl-branched 5-carbon chain diamine used primarily for hot melt adhesives. This discussion will focus on the use of this diamine for crystalline and amorphous polyamides through the proper adjustment of the ratio of MPMD to its codiamines, primarily hexamethylene diamine (HMDA). Both crystalline and amorphous polyamides produced from MPMD with HMDA as a codiamine have high tensile strength, high stiffness, good dimensional stability, and excellent thermal properties, such as glass transition temperature and heat deflection temperature. The resins can be produced with melt polymerization batch process. |
