IPC: C08G59/04
Filed: 1994-12-05
Abstract: PURPOSE:To obtain a novolak-type phenolic resin having a specific structure and useful as a raw material for a heat-resistant epoxy resin having high glass transition temperature and low elastic modulus. CONSTITUTION:This phenolic resin is expressed by formula I (R<1> to R<3> each is H, a hydrocarbon group or a. halogen; (n) is 2-50). The resin is preferably produced by polymerizing a p-isopropenyl phenol compound of formula II in the presence of an alkali catalyst such as NaOH at 140-250 deg.C.

Abstract: PURPOSE:To reduce the influence of a back shadow light, and to improve S/N by executing a phase modulation by an angular frequency omega with respect to a sample reflected light or a sample incident light, and separating a DC component, an omega component, and a 2omega component of a detecting light intensity signal.
