超支化聚酯可以明显的提高环氧树脂涂料的韧性

超支化聚酯可以明显的提高环氧树脂涂料的韧性超支化聚酯可以明显的提高环氧树脂涂料的韧性，即抗冲击性能，伴随超支化聚酯用量的增加，抗冲击性提高，当添加量为15%，抗冲击性能是原来的296%，并且不影响原环氧树脂基质的固化条件和速率，以及机械强度，这归因于超支化聚酯的塑化性能以及在环氧树脂相中的微粒结构。威海晨源化工新材料有限公司整理自《HyperbranchedPolymersinCationicPhotopolymerizationofEpoxySystems》M.SANGERMANO',G.MALUCELLI1,R.BONGIOVANNI',A.PFUOLA1*,A.HARDEN2,andN.REHNBERG2lDipartimentodiScienzadeiMaterialieIngegneriaChimicaPolitecnicodiToMo,C.soDucadegliAbruzzi24I-10129Torino,Italy2PerstorpSpecialtyChemicals,28480Perstorp,SwedenPOLYMERENGINEERINGANDSCIENCE,AUGUST2003,Vol.43,No.8，1461-1465Hyperbranchedpolyestercansignificantlyimprovethetoughnessofepoxycoating.Hyperbranchedpolyestercansignificantlyimprovethetoughnessofepoxycoating,i.eimpactresistance,withanincreaseintheamountofhyperbranchedpolyester,theimpactresistanceincreases,whiletheadditionlevelof15%,theimpactresistanceincreasesby296%andhavenoimpactontheepoxyresinmatrixcuringcondition,rate,andmechanicalstrength,whichisattributedtoplasticizingpropertiesofhyperbranchedpolyesterandparticlesstructureintheepoxyresinphase.WeihaiCYDendrimerTechnologyCo.LtdforwardsfromHyperbranchedPolymersinCationicPhotopolymerizationofEpoxySystemsM.SANGERMANO',G.MALUCELLI1,R.BONGIOVANNI',A.PFUOLA1*,A.HARDEN2,andN.REHNBERG2lDipartimentodiScienzadeiMaterialieIngegneriaChimicaPolitecnicodiToMo,C.soDucadegliAbruzzi24I-10129Torino,Italy2PerstorpSpecialtyChemicals,28480Perstorp,SwedenPOLYMERENGINEERINGANDSCIENCE,AUGUST2003,Vol.43,No.8,1461-1465
