Abstract
Acetylenic maleates, fumarates and related derivative compounds are new compositions of matter having the formula: EQU R.sub.1 O.sub.2 C--CH.dbd.CH--CO.sub.2 R.sub.2 wherein R.sub.1 may be an organic moiety containing at least two carbon atoms triply bonded one to the other as: EQU --C.tbd.C-- and R.sub.2 may be hydrogen, an organic moiety, or R.sub.1 ; suitable for use as liquid injection molding inhibitors either singly or in combination with themselves or other liquid injection molding inhibitors when used for the process of liquid injection molding curable compositions enabling an increase in the size of articles manufactured therefrom, which new compositions of matter cure into the polymerizable or curable resins thereby creating new compositions of matter as cured resins from which said articles of manufacture are produced.
