Abstract Liquid‐crystalline AB‐block copolymers poly[6‐(4′‐methoxy‐4‐biphenylyoxy)hexyl methacrylate]‐ block ‐polystyrene were synthesized by direct coupling of the homopolymers with functional end groups. Like the liquid‐crystalline homopolymer with mesogenic units in the side chain, all block copolymers show a nematic mesophase. The transition temperatures are hardly affected by the composition and molecular weight of the block copolymers.

Synthesis, polymerization and copolymerization of 5‐methyl‐3‐methylene‐2‐pyrrolidone

Die Makromolekulare Chemie (1990)

Marcel Van Beylen Celeste Samyn

Abstract A new lactam monomer containing a vinylidene group was synthesized, namely, 5‐methyl‐3‐methylene‐2‐pyrrolidone ( 4 ). The homopolymerization and copolymerization with methyl methacrylate and with styrene were studied. The copolymerization parameters r 1 and r 2 were also evaluated. Hydrolysis of the pendent lactam groups yields a polyelectrolyte (or homopolymer) with pendent γ‐amino acid units.

Polydepsipeptides: Ring‐opening polymerization of 3‐Methyl‐2, 5‐Morpholinedione, 3,6‐Dimethyl‐2,5‐morpholinedione and copolymerization thereof with D, L‐Lactide

Makromolekulare Chemie Macromolecular Symposia (1988)

Celest Samyn Marcel Van Beylen

Abstract Poly (ester‐amide)s were synthesized by ring‐opening polymerization of 2,5‐morpholinedione derivatives. The monomers: 3‐methyl‐ and 3,6‐dimethyl‐2,5‐morpholinedione were prepared first, and subsequently polymerized with tin(II) bis(2‐ethylhexanoate) as an initiator at 145°C in bulk. Copolymerizations with D, L‐lactide were also investigated; in this way copolymers with higher molecular weight were obtained, which provide materials with a wider range of properties.

Synthesis and nonlinear optical properties of high glass transition polyimides

Macromolecular Chemistry and Physics (1999)

Kurt Van den Broeck Thierry Verbiest Marcel Van Beylen André Persoons Celest Samyn

Nonlinear optical (NLO) polymers with glass transition temperatures (Tg) as high as 275°C were prepared by covalent bonding of a chromophore to the backbone of hydroxyl polyimides via a Mitsunobu reaction. NLO side-chain polyimides with different polymer backbones and different chromophores were prepared and characterized by second-harmonic generation. Poled films of the polymers have an excellent nonlinear optical response that is stable at elevated temperatures.
