Polyesters with aliphatic and cycloaliphatic backbone

acetaldehyde, acetone, acrylic acid, acetic acid. DL-lactide. meso-lactide. cyclic oligomers up to nonamer. 2.3 pentanedione. iactoyl lactic acid [Pg.527]

200-500 CIS- and frerrs-2-ethyl crotonic acid (major products) 200-500 cydohexen-1 -carboxylic acid, cyclohexanone [Pg.527]

3-butadiene, ethylene, CO , H 0. 3-buten-l-ol, 2-oxelanone, cyclopropanone. succinic anhydride, succtntc add monoethyl ester, succinic acid monobulyl ester, sucdnic acid monobutenyl ester, ethyl butenyl sucdnate. ethenyl bulenyl succinate, ethyl butenyl succinate, butyl bulenyl succinate, dimer (4t. 2 wt.%). crotonic acid (35.3), tnmer (12.5), letramer (2 9). isocratonic add (0.9). Small amounts of CO , propene. ketene, acetaldehyde, and l-bulyrolactone are foimed at higher temperatures due to decomposition of pnmary products [Pg.527]

As shown in the pyrogram of poly(L-lactide), the main pyrolysis products are CO and acetaldehyde. The pyrolysis probably takes place by a free radical mechanism including the following reactions [Pg.529]

For poly(caprolactone) the main reaction during pyrolysis is the formation of 5-hexenoic [Pg.531]
