The polymeric matrix used in this study was the poly(butylene
terephthalate) (PBT) POCAN B1505 (MFI 250[degrees]C/2.16kg: 16 g/10 min, [rho]: 1.31 g/[cm.sup.3], [T.sub.m]: 225[degrees]C) supplied by Lanxess GmbH.
A series of biodegradable copolyester, poly(butylene
ierephthalate-co-butylene adipate-co-ethylene terephthalate-co-ethylene adipate) (PBATE), were synthesized by direcl esterification and polycondensation, and these compounds were random copolymers according to their *H NMR spectra.

This complex has units producing polyethylene, synthetic rubbers, latex, propylene glycol, pyrolysis benzene and fractions of butene, butylene
succinate) (PBS) and poly(butylene
succinate-co-butylene adipate) (PBSA) are commercial synthetic polyesters with excellent biodegradability.

Typical hydrogenated styrene elastomers are composed of hard block (styrene) and soft block (ethylene, propylene, butylene
, etc.) polymers.
A new trend, according to Ted Klimek, who heads up PP development activities at Quantum, is toward random terpolymers of ethylene, butylene
and propylene as alternatives to traditional random ethylene-propylene copolymers for film heat-seal layers.
Export of diesel fuel increased by about 48 percent, absolute isopropyl alcohol 69 percent, liquid pyrolysis resin 27 percent, propylene 30 percent, while export of whole butylene
butadiene fractions - by 37 percent.
