Abstract
A process for the preparation of a (co)polymer containing at least one unit derived from a citraconimide by curing curable composition comprising at least one substituted or unsubstituted citraconimide and a sufficient amount of an anionic curing catalyst to convert at least 10% of the citraconic alkyl groups on the citraconimide units to alkylene bridges; at a temperature above the melting point of the citraconimide unit and the product of that curing process, are disclosed. The invention also relates to the cured oligomers and articles of manufacture embodying them. These novel, cured oligomers are thermoplastic and offer several advantageous properties.
