支化共聚聚酰胺6的制备与性能
Preparation and properties of branched copolymerized polyamide 6
摘要
Abstract
The random branched polyamide 6 containing a small amount of long branched structure has been prepared by using hexanolatctam as monomer and lysine as the branching monomer. The properties of the branched polyamide 6 were studied by FTIR,DSC,SAXS and rheological test. The results showed that as the AB2 trifunctional comonomer,lysine could copolymerized with hexanolatctam to prepared branched polyamide 6 containing long branched structure. The zero shear viscosity of the branched polyamide 6 increases,the shear thinning phenomenon becomes more obovious,which is favorable for processing. The crystallization ability and crystallization rate of the branched polyamide 6 are slightly lowered,but the mechanical properties of the linear polyamide 6 which is close to the viscosity are not much different,and the mechanical properties of the material are mainly affected by the viscosity. The introduction of long branches in the polyamide 6 makes it easier to orient the molecular chains in the machine direction.关键词
