The block polymers PCLgEC was preparing with extender chain 1,4 phenylene bis (2-oxazoline (PBO) by reacting of the prepolymers poly (e-caprolactone) produced by the ring opening polymersation of ε-caprolactone by adipic acidic with ethyl cellulosein the presence of a catalytic amount of titanium isopropoxide [Ti-(OCH 2 (CH 3) 2) 4 ]. The reaction was conducted at 170°C for 40 min the inert atmosphere. The expected structures of the polymers were confirmed by FTIR. Enzymatic degradations in

The biodegradation of polymers was observed by changing of BOD a long of 30 days.
