    摘要： The present invention relates to a process for the manufacture of foundry cores and moulds. To that end a mixture comprising a granular filler such as sand, a synthetic resin which cures under the influence of an acid and a ketone peroxide desensitized with one or more specific dialkyl esters of dicarboxylic acids is formed into a foundry core or mould and treated with S0 2 . The dialkyl ester should have the formula
    where

    n = 1-7 and
    R, and R 2 = a branched or non-branched alkyl group having 3 to 5 carbon atoms.

    摘要： The invention relates to peroxide compositions comprising a reactive diluent for the peroxide, wherein the diluent is either a component containing one or more vinyl ether group(s) and having a monomeric structure according to formula 1, (A-CH=CH-O)n-R, or is a suitable resinous compound comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s). In the formula A represents hydrogen or an alkyl group with 1-3 C atoms, and individual A groups may be different; R either represents an aliphatic group, optionally branched, with 1-20 C atoms, etc. or represents a polyethylene or polypropylene glycol with 2 to 120 glycol units, etc. and n is 1,2,3 or 4. The resinous compounds comprising, in a covalently built-in manner, a component containing one or more vinyl ether group(s) are obtained by reaction of: a) a first compound (the HVE-compound) containing at least one hydroxyl group and at least one vinyl ether group, and b) a second compound (the D/HIC-compound), being an isocyanate, reacting with formation of one or more urethane group(s), and c) a third compound (the G/P/HP-compound) chosen from the groups of (1) C2-6 glycols, (2) C5-20 polyols having 2-5 hydroxyl groups and (3) hydroxyl terminated polyester compounds, not being alkyd resins, having 1-5 free hydroxyl groups and from 2-50 monomeric ester units (the G/P/HP-compound), or mixtures thereof. The invention also relates to the preparation of such compositions and to the use of such reactive diluents for peroxides in radically curing of unsaturated polyester resins for structural applications.

    摘要： The present invention provides for a primer composition that will lower the VOC, maintain excellent performance of the primer, and improve the mix ratio. The primer composition contains a mixture of methyl ethyl ketone peroxide (MEKP) with a solvent. The solvent keeps the MEKP from decomposing while the potency to cure the prime is kept in the same required time.

    摘要： Novel unsaturated peroxide compositions of Structure A,
    are disclosed where the R-Q- grouping contains a polymerizable carbon-carbon double bound, i.e. R is, inter alia, alkyl of 1 to 18 carbons; Q is, inter alia,
    where -(X-Ri) shows the point of attachment of the X-R 1 group and (R)- shows the point of attachment of the R group to the Q diradical and R 2 and R 3 include hydrogen; -X- includes a direct bond and -R 1 is a peroxide-containing radical, e.g.,
    wherein R 6 , R 7 , R 8 and R 9 are, inter alia, alkyl of 1 to 4 carbons and R 10 includes t-alkyl of 4 to 12 carbons. Further, polymeric peroxide compositions derived from them and their uses are disclosed.
