  Core-First Synthesis of Three-, Four-, and Six-Armed Star-Shaped Poly(methyl methacrylate)s by Group Transfer Polymerization Using Phosphazene Base

  摘要：

  The core-first synthesis of three-, four-, and six-armed star-shaped poly(methyl methacrylate)s (PMMAs) with predicted molecular weights and narrow molecular weight distributions (M-w/M(n)s) was carried out by the t-BuP4-catalyzed group transfer polymerization (GTP) of methyl methacrylate (MMA) using the newly designed silyl enolates, such as 1,1,1-tris[2-methyl-1-(trimethylsilyloxy)prop-1-enyloxymethyl]propane (E(C(MTS)(3)), tetrakis{[2-niethyl-1-(trimethylsilyloxy)prop-1-enyloxy]methyl}methane (C(MTS)(4)), and bis{2,2,2-tris[2,methyl-1-(trimethylsilyloxy)prop-1-enyloxy]ethyl}ether (O-(C(MTS)(3))(2)), respectively. The absolute molecular weight (M-w(MALS)) of the obtained polymers proportionally increased with the increasing [MMA](0)/[initiator](0) ratio, and the highest molecular weight was ca. 132 kg mol(-1). Characterizations for the star-shaped PMMAs were conducted by cleavage and intrinsic viscosity [eta] experiments. Cleavage experiments of the star-shaped PMMAs provided the evidence for homogeneous growth of the each arm in the t-Bu-P-4-catalyzed GTP. The number of arm determined from the shrinking factors (g') of [eta] also supported the successful syntheses of the star-shaped polymers by the present core-first method. The versatility of this core-first method toward other methacrylic monomers was confirmed by the t-BuP4-catalyzed GTPs of allyl methacrylate (AMA), stearyl methacrylate (SMA), and 2-(dimethylamino)ethyl methacrylate (DMAEMA) using C(MTS)(4) as an initiator leading to well-defined star-shaped polymers.

  The present invention relates to multi-functional polymeric resin blends which have a defined average molecular weight distribution. Additionally each polymeric component of the blend has a polydispersity of from about 1.01 to about 2.50, The average functionality of the blend is from about 1.8 to about 4.0. More particularly, the present invention relates to poly(meth)acrylates having three or more functional groups. These highly functionalized resin blends are desirably prepared using controlled free radical polymerization techniques, such as single electron transfer living radical polymerization (SET-LRP) processes to produce a variety of blended resin systems which have tailored and enhanced properties.

The absolute molecular weight (M-w(MALS)) of the obtained polymers proportionally increased with the increasing [MMA](0)/[initiator](0) ratio, and the highest molecular weight was ca. 132 kg mol(-1). Characterizations for the star-shaped PMMAs were conducted by cleavage and intrinsic viscosity [eta] experiments. Cleavage experiments of the star-shaped PMMAs provided the evidence for homogeneous growth of the each arm in the t-Bu-P-4-catalyzed GTP. The number of arm determined from the shrinking factors (g') of [eta] also supported the successful syntheses of the star-shaped polymers by the present core-first method.
