  "abstract": "An initiator composition, including at least two compounds represented by the chemical formula R - CO - O - O - CO - R and a compound represented by R 1 - O - O - R 2, where R represents a C 2 -C 12 alkyl or a C 6 -C 10 aryl or substituted aryl, and R 1 and R 2 independently, at each occurrence, represent a C 1 -C 10 alkyl or a C 6 -C 10 aryl.",
  "claims": [
    "1. An initiator composition, comprising 75 parts by weight of at least two first peroxides and 25 parts by weight of a second peroxide, wherein the at least two first peroxides comprise 25 parts by weight of benzoyl peroxide, 30 parts by weight of 2,4-dichlorobenzene acyl peroxide, and 20 parts by weight of lauroyl peroxide, and the second peroxide is di-t-butyl peroxide.",
    "2. An initiator composition, comprising 95 parts by weight of at least two first peroxides and 5 parts by weight of a second peroxide, wherein the at least two first peroxides comprise 35 parts by weight of benzoyl peroxide, 40 parts by weight of 2,4-dichlorobenzene acyl peroxide, 10 parts by weight of lauroyl peroxide, and 10 parts by weight of diacetyl peroxide, and the second peroxide is t-butyl cumyl peroxide.",
    "3. An initiator composition, comprising 90 parts by weight of at least two first peroxides and 10 parts by weight of a second peroxide, wherein the at least two first peroxides comprise 40 parts by weight of benzoyl peroxide and 50 parts by weight of 2,4-dichlorobenzene acyl peroxide, and the second peroxide is dicumyl peroxide.",
    "4. An initiator composition for expediting curing of an unsaturated polyester resin at room temperature, the initiator composition comprising: at least two first peroxides selected from the group consisting of benzoyl peroxide, 2,4-dichlorobenzene acyl peroxide, lauroyl peroxide, and diacetyl peroxide; a second peroxide selected from the group consisting of dicumyl peroxide, di-t-butyl peroxide, and t-butyl cumyl peroxide; and a carboxylic ester peroxide selected from the group consisting of tert-butyl peroxybenzoate (TBPB), tert-butyl peroxy diethyl acetate, t-butyl peroctoate (TBPO); wherein: the initiator composition comprises between 70 and 85 parts by weight of the at least two first peroxides, between 5 and 15 parts by weight of the second peroxide, and between 5 and 15 parts by weight of the carboxylic ester peroxide.",
    "5. The initiator composition of claim 4, wherein the initiator composition expedites the curing of an unsaturated polyester resin at a temperature not higher than 15° C.",
    "6. An initiator composition, comprising at least two first peroxides, a second peroxide, and a carboxylic ester peroxide; wherein the at least two first peroxides are 75 parts by weight; the second peroxide is 12 parts by weight; the carboxylic ester peroxide is 13 parts by weight; the at least two first peroxides comprise 35 parts by weight of benzoyl peroxide and 40 parts by weight of 2,4-dichlorobenzene acyl peroxide; the second peroxide is dicumyl peroxide; and the carboxylic ester peroxide is tert-butyl peroxybenzoate."
