Diblock copolymers of poly(methylene-b-ε-caprolactone) (PM-b-PCL) were synthesized in two steps: (a) polyhomologation, to obtain following oxidative cleavage of the carbon-boron, (PM, block1), an α-hydroxyl-ω-Me polymethylene (PMOH, CH3-[CH2]m-OH). Following transfer reaction to the ring-opening polymerization catalyst and (b) ring-opening polymerization (ROP) of ε-caprolactone (CL) (PCL, block2). In addition, a series of homopolymers derived from poly(ε-caprolactone) (PCL) oligoesters containing an end group of docosyl (CH3-[CH2]21- or C22) (C22-PCL) were obtained as a model to compare their phys. properties by DSC with those of PM-b-PCL. The oligomers derived from PM-b-PCL and C22-PCL were characterized by 1H and 13C NMR, AFM, DSC, GPC and MALDI-TOF. PM-b-PCL and C22-PCL were evaluated as compatibilizers for PE/PCL polymer blends. Identification and anal. of optimized blocks of PM-b-PCL by POM and SEM showed improved mixing of PE/PCL blends.
