Abstract: In this study, an epoxy resin (diglycidyl ether of bisphenol A) was modified with triblock copolymers: poly(ethylene glycol)–poly(propylene glycol)–poly(ethylene glycol) (PEG‐PPG‐PEG) or PPG‐PEG‐PPG, with 10 wt% PEG in their structure, referred to as EPE and PEP,… read more here.

Abstract: Star and linear block copolymers of [poly(4-vinylpyridine)-block-polystyrene]n [(P4VP-b-PS)n] and [polystyrene-block-poly(4-vinylpyridine)]n [(PS-b-P4VP)n] (n = 1–4) with similar chemical composition but different block sequence were synthesized by RAFT polymerization. Star (P4VP-b-PS)n is composed of a jointed P4VP… read more here.
