ABSTRACT:
Polyurethane resins having excellent hydrolysis resistance are prepared from copolymerized caprolactone polyol obtained by the copolymerization of .epsilon.-caprolactone with trimethylcaprolactone having side chains as a diol component. The polyurethane resins so-obtained have excellent hydrolysis resistance, and retain high levels of mechanical strength, more excellent resistance under high heat and moisture conditions, etc., thereby maintaining a good balance of properties and are useful in a very wide variety of forms including spandex, rigid or flexible urethane foams, thermoplastic urethane elastomers, thermosetting urethane elastomers, adhesives, synthetic leather, and paints, etc.
