摘要:
A thermosetting resin composition comprising an N,N'-bismaleimide compound and an allylated phenol novolak resin having partially or wholly allyl-etherified phenolic hydroxyl groups and substantially no nucleous-substituted allyl group.
摘要:
A chlorine-containing resin is prevented from degradation due to heat and light by addition of a novolac type epoxy compound of the formula, ##STR1## wherein R is hydrogen or C.sub.1 - C.sub.4 alkyl, and n is a number of 5 to 15.
摘要:
A tar-urethane composition comprising (1) an isocyanate-reactive tar obtained by reacting a tar produced as a by-product in the phenol synthesis via hydroperoxides with a formaldehyde in the presence of a basic catalyst and in the presence or absence of at least one phenol compound and (2) a polyisocyanate, which is useful as coating agents, materials for pavement, floor linings, sealing materials and the like.
摘要:
A light control sheet capable of scattering an incident light of particular incident angle is produced by a method composed of preparing a film of a composition containing at least two photopolymerizable components having different refractive indexes, irradiating on the film a light from a particular direction, and obtaining a cured film of the light control sheet product. Such other light control sheets as capable of scattering a plurality of incident lights each of particular incident angle are obtained by modification of the above-mentioned method.
