Studies on Multihollow PUA-EMA-St Crosslinked Copolymer Beads: Synthesis and Hollow Structure

Abstract:

Article Preview

The multihollow and elastomeric beads from polyurethane acrylate (PUA), ethyl methacrylate (EMA) and styrene (St) are prepared by suspension polymerization using n-heptane as porogen and 1,2-divinylbenzene (DVB) as crosslinking agent. The SEM results show that the beads of PUA-EMA-St crosslinked copolymers have many and large hollows on their surfaces and interiors, and the hollow sizes are dependence of the copolymer composition and the dosages of porogen. Average hollow diameters decrease as the dosages of the contents of PUA and porogen decrease.
