Disclosed are acid hardenable phenolic resin compositions and novolac compositions modified with about 5 to about 15% by weight of at least one reactive diluent selected from the group consisting of benzylic alcohol, benzylic ether, ethylene glycol, 1,3-butylene glycol, monoallyl or methylallyl ethe
Disclosed are acid hardenable phenolic resin compositions and novolac compositions modified with about 5 to about 15% by weight of at least one reactive diluent selected from the group consisting of benzylic alcohol, benzylic ether, ethylene glycol, 1,3-butylene glycol, monoallyl or methylallyl ethers of poly(methylol) alkanes, monoallyl ether of glycerine, allyl or methallyl glycidyl ether, N-acylated arylamine, N-acylated naphthylamine, N-substituted arylsulfonamide, and N-substituted arylamine. The reactive diluent can be used to improve impact resistance and flexibility of the acid hardenable phenolic resin. Preferably, the methods for modifying mix life of acid hardenable phenolic resin by use of aryl phosphite and benzylic alcohol, and methods for modifying novolac resins, as well as methods for making the present compositions and products, such as coiled filament pipe and laminate panels, employing the compositions are also disclosed.

[ What is claimed is:] [1.] A composition for improving impact resistance and flexibility of acid hardenable phenolic resole resin comprising:(a) an acid hardenable phenolic resole resin;(b) about 5 to about 15% by weight of at least one additive selected from the group consisting of:substituted ben
[ What is claimed is:] [1.] A composition for improving impact resistance and flexibility of acid hardenable phenolic resole resin comprising:(a) an acid hardenable phenolic resole resin;(b) about 5 to about 15% by weight of at least one additive selected from the group consisting of:substituted benzylic alcohol having the Formula I: [ STR 20 ] wherein R.sup.1 is independently selected from the group consisting of H, all having 1 to 4 carbon atoms, and alkoxy having 1 to 4 carbon atoms, R.sup.2 is selected from the group consisting of H and alkyl having 1 to 4 carbon atoms, R.sup.3 is a moiety of formula --OR.sup.4 wherein R.sup.4 is selected from alkyl having 1 to 4 carbon atoms and aryl having 6 to 7 carbon atoms, wherein R.sup.1, R.sup.2 and R.sup.3 are not simultaneously H;benzylic ether having the Formula III: [ STR 21 ] wherein each R.sup.1, each R.sup.2 and each R.sup.3 are independently H or defined as in Formula I, 1,3-butylene glycol, monoallyl or methylallyl ethers of poly(methylol)alkanes, monoallyl ether of glycerine, allyl or methylallyl glycidyl ether, N-acylated naphthylamnine, and N-substituted arylsulfonamide; and(c) a hardening agent selected from the group consisting of organic acid, mineral acid, latent acid, and mixtures thereof.
