摘要

Cinnamoyloxyethyl methacrylate (CEMA) was synthesized by teh reaction of cinnamoyl chloride (CMC) and 2-hydroxyethyl methacrylate (HEMA). Its copolymers with stearyl methacrylate (SMA) were synthesized using benzoyl peroxide (BPO) as an initiator. The synthesized copolymers, poly(SMA-co-CEMA)s (PSCMAs), were photocrosslinked by UV light irradiation. The structures of the products were confirmed by IR and NMR spectroscopies. The thermal properties of the synthesized polymers were determined by DSC. The crystalline melting temperature of crosslinked PSCMA was decreased with increasing CEMA content in the feed. The oil absorptivities of the synthesized polymers were evaluated by teh ASTM method (F726-81). The highest oil absorptivity of crosslinked PSCMA on poly(ethylene terephthalate) (PET) nonwoven fiber (NWF) was 610% in 10% crude oil diluted with toluene when the mol percentage of CEMA to SMA in the feed was 7.5.
