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

Abstract
The polarographic behaviour of hydrolyzed propene‐maleic anhydride copolymers in the interval pH 2.0–11.0 has been investigated by differential pulse polarography in aqueous lithium chloride solution at 25°C. In dependence on the pH‐value, one, two or three signals, belonging to the acid groups in the copolymer, appear in the polarograms. Three apparent polarographic acid constants have been determined graphically from the changes in the half‐wave potential of the separate peaks in correlation with pH.

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
Ethylene vinyl acetate (EVA) copolymers with different amounts of vinyl acetate were melt-functionalized with maleic anhydride. The effect of benzoyl peroxide, t-butyl perbenzoate, and dicumyl peroxide (DCP) as free-radical initiators on the functionalization performance was studied. The crosslinkin
