ABSTRACT:
Formed products such as foams, fabrics for industrial materials, filaments, nonwoven fabrics, composite materials and films which are degradable after use with ease in the natural environment are prepared by using a high molecular weight aliphatic polyester obtained by direct polycondensation of an aliphatic polyhydric alcohol with aliphatic polybasic acid or additionally hydroxycarboxylic acid or oligomers of these materials in a reaction mixture containing a solvent.
Foams have excellent thermal insulation and strength; fabrics are excellent in thermal insulation, strength and elongation and can be used for industrial materials; filaments have sufficient strength, flexibility and degradability in a living body and can be used for bioabsorbable surgical filament and fishing lines; nonwoven fabrics can be obtained by bonding a web of filaments and have excellent strength and feeling; composite materials can be prepared by adhering or impregnating fiber, paper, film and others of cellulosics and have excellent strength and water resistance, good flexibility and folding resistance, simultaneously have degradability in the natural environment, and can dissolve polymer films on the surface with ease under alkaline conditions to recover cellulosics alone; and films are excellent in heat resistance and strength.
