amino-polymer modified functional macroporous PHIPE–PGMA–TETA, was prepared conveniently. Gold nanoparticles could be easily in situ prepared and immobilized on the surface of PHIPE–PGMA–TETA. Characterization by scanning electron microscopy (SEM), EDX-mapping and TGA showed that PHIPE–PGMA–TETA was immobilized by the gold nanoparticles, and presented good catalytic properties. Moreover, the macroporous

Polymer chain architecture is a critically important chain parameter governing intrinsically the properties and applications of polymers. The rapid developments in "living"/controlledpolymerization techniques, particularly the controlled radical polymerization techniques, in the past two decades have enabled the precision synthesis of novel polymers having a great variety of complex yet well-defined

A polymer having a polymerizable group and an alkyleneoxy groups on side chains thereof, and a polymerizable composition containing the polymer. The polymerizable composition preferably contains a polymerizable compound and a polymerization initiator. Also provided is a planographic printing plate precursor having a polymerizable layer on a hydrophilic support, the polymerizable layer containing a polymer having a polymerizable on a side chain thereof. The planographic printing plate precursor can form an image without being subjected to an alkali development. An undercoat layer containing a specific copolymer may be provided between the support and the photopolymerizable layer.

A methodology is described for the synthesis of polyolefin containing block-copolymers using a catalytic postpolymerization modification strategy. Common polyolefin grades may be converted into macroinitiators using a cross-metathesis reaction. The functionalized polyolefins may then be used to initiate living: coordinative ring opening polymerization of cyclic ester monomer, anionic ring opening polymerization of epoxide monomer, and radical polymerization of vinylic monomer, to yield the corresponding block copolymers.
