## Abstract Copolymers of transβ1,4βpolyisoprene containing 2,2 molβ%, 5,0 molβ% and 9,8 molβ% epoxidized units were crystallized from the melt at temperatures (__T__~c~) of 25 to 36Β°C. The progress of the crystallization was monitored, and final crystallinities at __T__~c~ and after cooling to 25Β°
## Abstract Crystals of fractionated __trans__β1,4βpolyisoprene (TPI) were grown from amyl acetate solution at two weight fractions, 5.7 Γ 10^β4^ and 0.011; for the lower concentration a precooling followed by heating and then crystallization at temperatures in the 10β32Β°C range was used, while for
