摘要:
An aminated polymer having excellent adhesion, printability, and compatibility in polymer blends or the like which are obtained by introducing an amino group, into an isotactic .alpha.-olefin polymer having an olefinic unsaturated bond at its terminus is disclosed. The terminal unsaturated isotactic or syndiotactic .alpha.-olefin polymer is obtained by polymerizing an .alpha.-olefin with a catalyst comprising the combination of a metallocene compound and an alumoxane, and the amino group is obtained by the amination of the terminal unsaturated group, by the addition of a compound containing the corresponding functional group to the unsaturated bond, or by the conversion of a precursor polymer containing a precursor of the functional group into a polymer containing the functional group desired.

摘要:
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 ethlenically unsaturated monomer is an ester of 1 mole of tricyclo[5,2,1,0.sup.2,6 ]decanedimethanol with 2 moles of a mixture of acrylic acid and metharcylic 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 cyclopentadine are also used in place of the tricyclo [5,2,1,0.sup.2,6 ]decanedimthanol which is a Diels-Alder adduct of two moles of cyclopentadiene.
