Network copolyesters were prepared from glycerol (Yg) and sebacic acid (10) with 10 -90 mol % of either succinic acid (4), 1,12-dodecanedicarboxylic acid ( 14), 1,18-octadecanedicarboxylic acid (20), or terephthalic acid (T). Prepolymers prepared by melt-polycondensation were cast from dimethylforma
## Abstract Poly(hexamethylene adipate) copolymers with 10โ40 molโ% (in feed) of aliphatic diamines of various methylene chain lengths were prepared by melt polycondensation. __In vitro__ degradation was performed in buffer solution at 37ยฐC with a lipase and was evaluated by weight loss of the film
## Abstract **Summary:** The title polymers, in which both the stem and the graft are biodegradable, have been synthesized for the first time in a oneโpot, lipaseโcatalyzed, graftโpolymerization reaction (in bulk, at 70โยฐC) of __ฮฒ__โbutyrolactone (__ฮฒ__โBL) and __ฮต__โcaprolactone (__ฮต__โCL) onto ch
