Abstract
The prepolymers for a novel oil absorbent were synthesized by copolymerizing
styrene with 2-ethylhexyl acrylate (EHA), lauryl acrylate (LA), lauryl methacrylate
(LMA), and stearyl acrylate (SA). Suspension polymerization was carried out using
benzoyl peroxide (BPO) as an initiator with a varying monomer feed ratio, and the
copolymers were characterized by FTIR, 1H-NMR, DSC, and a solubility test. The
copolymers were random copolymers with a single phase, and their compositions were
similar to those in the monomer feed. The Tg of the copolymer could be controlled by
varying the styrene/acrylate ratio. Acrylates introduced the crosslinking to linear
polymers as a side reaction. Crosslinked copolymers were synthesized by adding divinylbenzene
(DVB) as a crosslinking agent. At a low degree of crosslinking (0.5 wt %
DVB), the Tg of the crosslinked copolymers was lower than or similar to that of the
uncrosslinked ones. At a high degree of crosslinking, the Tg increased with increasing
crosslinking density.
