Silane-modified phenolic resins and applications thereof.U.S. patent: 7,259,221 Issued: August 21, 2007 Inventors: Raj B. Durairaj, C. Michael Walkup and Mark A. Lawrence Key statement: A silane-modified phenolic resin is prepared by reacting a phenolic compound (e.g., resorcinol resorcinol /re·sor·ci·nol/ (re-zor´si-nol) a bactericidal, fungicidal, keratolytic, exfoliative, and antipruritic agent, used especially as a topical keratolytic in the treatment of acne and other dermatoses. ) with an aldehyde aldehyde (ăl`dəhīd) [alcohol + New Lat. dehydrogenatus=dehydrogenated], any of a class of organic compounds that contain the carbonyl group, and in which the carbonyl group is bonded to at least one hydrogen; the general to produce a phenolic novolak resin. The phenolic novolak resin is further reacted with at least one silane compound to produce the silane-modified phenolic resin. The reaction is typically carried out in the presence of an acid or base catalyst. The resulting resin has a lower softening point and can be used as a methylene methylene /meth·y·lene/ (meth?i-len) the bivalent hydrocarbon radical —CH2— or CH2dbond. meth·yl·ene n. acceptor acceptor - Finite State Machine compound in a vulcanizable rubber composition. |
