Styrene-maleic anhydride (SMA) copolymers containing either 7 or 14% maleic anhydride were filled with either pine flour or dry-process aspen fiber from a medium density fiberboard (MDF) plant. Material properties of the filled and unfilled SMA plastics were compared with those of aspen-fiber-filled
A series of maleic anhydride (MA)Èvinyl acetate (VA), MAÈmethyl methacrylate (MM) and MAÈstyrene (S) copolymers were prepared and characterized. By employing various amounts of initiator, MAÈVA, MAÈMM and MAÈS copolymers with molecular weights ranging between 18 000 and 219 000 were obtained. The "i
A copolymer (MW = 1800) of styrene (St) and maleicanhydride (MAn) wasesterified with an excess amount of an alcohol mixture, and then the relation between the esterification rates of the individual alcohols and the contents of the esters in the esterific copolymer was examined. At first, the rate co
