Abstract
PURPOSE: To convert a polyester elastomer having relatively low melt viscosity to a highly viscous one, easily, keeping its good transparency, by mixing a metal salt of a dimer acid under melting.
CONSTITUTION: A block-copolymerized poly(etherester) elastomer derived from a dicarboxylic acid composed mainly of terephthalic acid or its ester-forming derivative and a polyalkylene glycol having a molecular weight of 600W4,000, is mixed with 0.4W10wt% of a dimer acid salt of a Ia group metal of the periodic table, pref. lithium, sodium or potassium, under melting. The dimer acid may contain ≤35% of monomer acids and trimer acids which are by-products of the synthesis. The metallic salt may be a mixture, and ≥90% of the carboxyl group is pref. neutralized.
