Abstract

PURPOSE:To obtain an electronic component sealing agent quite low in melt viscosity, high in tenacity, and excellent in heat- and humidity-resistant features by a method wherein such a sealing agent is composed of a specified aromatic polyester. CONSTITUTION:The agent of this design is an aromatic polyester which includes structural units represented by formulas I-IV. Unit I occupies 40-90mol% of the entirety, II+III+IV occupies 60-10mol%, mol ratio II/III is 8/2-2/8, and IV/[II+III+IV] occupies 0-40mol% of the entirety. There exists a 'meta-' or 'para-' relationship, wherein the meta/para ratio is 0/100-35/65, between carbonyl groups in dicarboxylic acids in formulas I and III. In the formulas, R represents one or more substitutional groups selected out of t-butyl groups and phenyl groups, X represents a group such as formula V, and Y represents a group such as formula VI. This method yields an electronic component sealing agent, low in melt viscosity, high in tenacity, and excellent in humidity- and heat-resistant features.
