The T and degree of crystallinity affect the low-temperature adhesive properties; the peel strength is relatively low when the T, is appreciably above the use temperature. The T, degree of crystallinity, and melting point affect the hightemperature adhesive properties. A hot-melt adhesive with high peel and tensile shear strengths from 0 to 120°C is the polyester of 1,4-butanediol and trans-l,4-cyclohexanedicarboxylic acid.
