Zusammenfassung: | 1409962 Polyester resin catalysts AIR PRODUCTS & CHEMICALS Inc 19 June 1973 [1 Sept 1972] 29086/73 Heading C3P Unsaturated polyester resins are cured with a combination of a free radical initiator and a metal co-ordination complex formed in solution from a metal salt and a tertiary amine of which at least 25% molar is triethylene diamine, the molar ratios of amine to metal salt being at least 1 : 1. Also present may be an unsaturated monomer, e.g. styrene, a thermoplastic resin, e.g. polymethyl methacrylate, filler, thickener, glass reinforcement, and alkylated polyvinyl pyrrolidone. Exemplified initiators are t-butyl perbenzoate or a mixture thereof with t-butyl peroctoate, CoCl 2 , CoCl 2 /ZnCl 2 , or cobalt naphthenate or acetate and triethylene diamine or mixtures thereof with dimethylethanolamine. Dipropyleneglycol, glycerol and dioctyl phthalate are used as solvents. |
