Diglycidyl ester

Cycloaliphatic Epoxy Resins. This family of aUphatic, low viscosity epoxy resins consists of two principal varieties, cycloolefins epoxidized with peracetic acid and diglycidyl esters of cycHc dicarboxyhc acids. [Pg.364]

In some cases, network structure is modified by aminolysis reactions25. An example is the polymer formed from diglycidylic ester of o-phthalic acid and diaminodiphenilmethane. Aminolysis makes the chain between crosslinks shorter and influences the properties of the polymer (dynamic shear modulus in a rubbery... [Pg.54]

Tougher polymers of somewhat lower Tg are obtained from glycidyl esters such as the diglycidyl ester of hexahydrophthalic acid (Araldite CY-184 from Huntsman). The glycidyl esters are prepared by reacting the corresponding cycloaliphatic carboxylic acid with epichlorohydrin and dehydrohalogenat-ing with NaOH. [Pg.600]

Attempts are also known to relate the type of time dependence of viscosity in the curing process to the kinetics of the reaction. Thus, upon curing of diglycidyl ester of Bisphenol A by triethanolamine, the viscosity curve Tj (t) was approximated by two linear segments [40]. The appearance of an inflection point is explained by the authors on the basis of the formation of a meshing network an the linearity of the tj (t) dependence in the first party by the fact that a curing reaction is of a zeroth order.

Epoxidation of diglycidyl esters XXXVI (Scheme 40) which can be synthesized directly from the corresponding dicarboxylic acids has been an object of considerable interest [21 -23]. Such diepoxy compounds have found applications thanks to their low viscosity, high adhesion and good dielectric properties. However, there is a disadvantage in low heat resistance (TM below 100 °C) and unsatisfactory mechanical strength. [Pg.70]

There were no difficulties when 3-methyl substituted 4-cyclohexene-1,2-di-carboxylic acid or its diglycidyl ester was epoxidized with PAA. The yield and properties of the synthesized triepoxides (XXXVII, Scheme 41) are given in Table 7 [25,26]. [Pg.71]

For compounds of epoxy resins based on epoxy-diane ohgomers and resorcinol diglycidyle esters set with amine curing agents, the dependence of Tad oil the content and type of the modifying additive displays distinct maxima. The adhesion strength is enhanced most when the SKD-KTRA rubber is applied at 20% (see Figs. 3.17 and 3.18). With SKN-KTR as modifier the effect is less. [Pg.157]

Sampei et al. [187] reported that polyaddition of 2,5-norbomadiene-2,3-dicarboxylic acid diglycidyl ester to adipoyl chloride gave a polyester containing norbomadiene residues in the polymer backbone and in the pendant groups. When a photochemical rearrangement of norbomadiene residues took place in polymer films, the rate of the photochemical reactions in the polymer backbones was higher than that in the side chains [187].
