  • Powder composition of crystalline polyesters containing end methacrylyl groups
    Patent number: 5639560
    Abstract: A radiation-curable powder composition for use as varnish or paint which comprises at least one crystalline polyester containing end methacrylyl groups comprising the reaction products of glycidyl methacrylate and of a crystalline polyester containing end carboxyl groups is described. The said crystalline polyester containing end carboxyl groups is either(a) a polyester which is the reaction product of(1) an acid constituent which contains (a.1.1) 85 to 100 mol % of terephthalic acid or of 1,4-cyclohexanedicarboxylic acid and (a.1.2) 0 to 15 mol % of at least one other aliphatic, cycloaliphatic or aromatic di- or polycarboxylic acid having from 4 to 14 carbon atoms, and(2) an alcohol constituent which contains (a.2.1) 85 to 100 mol % of a saturated, straight-chain, aliphatic diol having from 2 to 12 carbon atoms and (a.2.
