  • Patent number: 9387281
    Abstract: A composition comprising at least one polymer having the structure A-B-A?, wherein A and A? may be the same or different and each is a degradable polyester component and wherein B is the reaction product resulting from the reaction between a diol, having one or more pendant oligomeric or polymeric groups, and A and A?. Additionally, a bioresorbable patch comprising: (a) an adhesion barrier component comprising the composition in the form of a film; and (b) an adhesive component comprising (i) at least one synthetic adhesive polymer and/or (ii) at least one polysaccharide. Also, a method of wound healing, comprising administering the composition or apply the patch to a patient.

  • Publication number: 20160017080
    Abstract: The invention is directed to polysiloxane based block copolymers that comprise siloxane units and units derived from diol compounds comprising at least one pendant oligomeric or polymeric group. The block copolymers according to the invention surprisingly allows any glassware used during its preparation to be washed cleaned with water. The block copolymer can be used in ophthalmic lenses, and may be useful in providing contact lens formulations which are water processable.
