摘要： An aromatic polyester consisting of 40-70 mol % of unit I derived from p-hydroxybenzoic acid, 1-8 mol % of unit II derived from m-hydroxybenzoic acid or isophthalic acid, 6-36 mol % of units III and IV derived from terephthalic acid and 2,6-naphthalene dicarboxylic acid, respectively, and 10-40 mol % of unit V derived from a symmetrical dihydroxy compound can be melt molded at a temperature of up to 330.degree. C. into an article having improved mechanical and thermal properties. An aromatic polyesteramide consisting of components I to V and unit VI having an anilino group is also provided. A filled composition is obtained by blending the polyester or polyesteramide with an inorganic filler. A magnetic resin composition is obtained by blending the polyester or polyesteramide with a magnetic powder.

摘要： Copolyesteramides consisting of specific units can be injection molded at a low temperature into a part having a high heat distortion temperature. A filled composition is obtained by blending the copolyesteramide with an inorganic filler. A magnetic resin composition is obtained by blending the copolyesteramide with an magnetic powder.The copolyesteramide consists essentially of units , , , , and of the following formulae: ##STR1## wherein each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is independently at least one divalent radical selected from the group consisting of para-phenylene, 2,6-naphthalene, and 4,4'-biphenylene,R.sup.5 is a para- or meta-phenylene radical,X.sup.1 is --NH--,X.sup.2 is --NH--, --O-- or ##STR2##
