Based on the structure analysis indicate that polymerization of 2,2-dimethyl-1,3-propandiol and e-caprolactone monomers produced polymers with various molecular weights, which depend on the ratio of e-caprolactone / 2,2-dimethyl-1,3-propandiol used in polymerization. The reactivity of CL monomer...
The comparison, based on the structure of the initiator and on the polymerization features (molar mass, molar mass distribution, side reactions) reveals some differences especially in the number of active polymer chains per metal and in the occurrence of some transfer reactions with Ln(BH4)3(THF...

Japan (Received March 18, 1991) ABSTRACT: Ringed spherulites were found in binary blends of poly(e-caprolactone) (PCL) and e-caprolactone-butadiene diblock copolymer (PCL-b-PB), while the regularly banded structure could not be observed in an oligomeric blend of PCL and polybutadiene (PB)....
Previous studies [2] have shown that PCL can be used as a polymer matrix for the preparation of polymer electrolytes due to the existence of carbonyl functional groups in its backbone structure. Thus, the ability of PCL as a host polymer is due to the presence of carbonyl groups in its ...

The core-arm structure of the star polymer was believed to be the main reason for their interesting properties, and it also required special preparation procedures. Generally, two methods were com- monly employed to prepare the star polymers, that is, the 'arm-first' and 'core-first' ...
