摘      要：正 The Crystallization behavior of PEG side chain（Mw=1100,5000 g/mol）in Comb-likePoly（acrylic acid）-g-Poly（ethylene glycol）Copolymers were analyzed by *** resultsindicate the melting characteristics and crystallization behaviors of the mPEG side-chain incopolymer bulks were drastically different from homo-polymer bulks of the ***,the crystal morphologies of the comb-like copolymers in thin films prepared by means of spin-coating on glass substrates were observed by phase contrast *** is noticeable that a lotof specially interesting branched crystal morphologies were formed through DLA processes.
