  • Publication number: 20200277445
    Abstract: Disclosed is a terminally functionalized polysiloxane urethane polymer comprising: polysiloxane segments comprising from 50 to 98% by weight based on the total polymer weight; urethane segments comprising from 2 to 50% by weight based on the total polymer weight; and terminal functional groups selected from (meth)acrylate functional groups, alkoxysilyl functional groups and mixtures thereof. The terminally functionalized polysiloxane urethane polymer finds use in liquid optically clear adhesive formulations wherein it can provide dual photo and moisture cure properties. In some embodiments cured reaction products of the liquid optically clear adhesive composition prepared with the terminally functionalized polysiloxane urethane polymer exhibit low haze of 2% or less and low yellowness b* values of 2 or less as prepared and after aging testing.

  • Patent number: 10329369
    Abstract: The present invention relates to controlled radical polymerization processes for making branched-functionalized block polyacrylate polymers and compositions formed therefrom. In particular, such reaction products are formed by ensuring that the reaction products are substantially flowable and non-gelling, indicating that substantially no polymerization has occurred. The branched-functionalized block polyacrylates may be further functionalized and/or polymerized.
