| abstract | PURPOSE:To obtain the title resin having excellent moisture resistance, heat resistance, thermal stability and low birefringence, by polymerizing an esterification product of tricyclodecane-and/or pentacyclopentadecanedimethanol and (meth)acrylic acid and a specified (meth)acrylate. CONSTITUTION:1 mole of tricyclodecanedimethanol and/or pentacyclopentadecanedimethanol is esterified with 2 moles of a mixture of methacrylic acid with acrylic acid to obtain a mixture of di(meth)acrylate (A) as the reaction product. 100 pts.wt. ethylenically unsatd. monomer consisting of 50-99wt.% component A and 50-1wt.% (meth)acrylate (B) of formula I (wherein R1 is a group of formulas II and III; R2 is H, CH3) is polymerized in the presence of 0.01-20 pts.wt. radical initiator (e.g., benzoyl peroxide) in air or in an inert gas at 0-150 deg.C. |
