| Abstract | © An optical resin consisting essentially of a radical polymerization polymer of an ethylenically unsaturated monomer, characterized in that at least a major part of the ethylenically unsaturated monomer is an ester of 1 mole of tricyclo[5,2,1,02'6]decanedimethanol with 2 moles of a mixture of acrylic acid and methacrylic acid. Because the resin is a polymer obtained from the restricted monomer as specified above, the resin possesses high thermal resistance and high heat stability as well as low hygroscopic property. Dimethanol compounds from higher Diels-Alder adducts of cyclopentadiene are also used in place of the tricyclo [5,2,1, 02'6]decanedimethanol which is a Diels-Alder adduct of two moles of cyclopentadiene. |
