| titleOfInvention | Suspension polymerisation process utilising a combination of peroxide initiators |
| abstract | Disclosed is the use of a combination of diacyl peroxides with an aromatic amine of formula Ar-N(R1)(R2) (where R1 are R2 are disclosed herein, and Ar is an optionally substituted aryl group, examples of which include N-ethyl-N-hydroxyethyl aniline, N,N-bis hydroxyethyl aniline, N-ethyl-N-hydroxyethyl-p-toluidine and N,N-bis 2-hydroxyethyl)-p-toluidine), as a redox initiating system in a process for the manufacture of solid polyester granules by suspension polymerisation, wherein the combination of diacyl peroxides comprises diaroyl peroxide (such as dibenzoyl peroxide and 2,4-dichlorobenzoyl peroxide) and dialkanoyl peroxide (such as dilauroyl peroxide, diacetyl peroxide, disuccinyl peroxide, di(3,5,5-trimethylhexanoyl) peroxide, and didecanoyl peroxide) having a diaroyl peroxide to dialkanoyl peroxide mole ratio that is equal to or greater than 1:1. Also disclosed is a process for the preparation of solid polyester granules comprising: (i) preparing a solution of unsaturated polyester and a combination of diacyl peroxides in styrene, wherein the combination of diacyl peroxides comprises diaroyl peroxide and dialkanoyl peroxide having a diaroyl peroxide to dialkanoyl peroxide mole ratio that is equal to or greater than 1:1, (ii) emulsifying said solution in water to provide a stabilised oil-in-water emulsion, (iii) adding to said emulsion an aromatic amine of formula Ar-N(R1)(R2) as defined above, such that reaction of said aromatic amine with each of the diaroyl and dialkanoyl peroxides generates a radical flux capable of initiating polymerisation of the unsaturated polyester and the styrene. |
