Meth acrylic Monomers

Various (meth)acrylic monomers have been successfully grafted onto polyolefins. Most studies deal with functional monomers. Grafting yields obtained with PP are usually low (<20%) and are dependent on the particular monomer. Liu et al.jM carried out a comparative study on the grafting of various functional methacrylates onto PP. The experiments were performed in a batch mixer at 180 °C with 7 wt% monomer and 0.05 wt% 22 as an initiator. Grafting levels (wt%) obtained under these conditions were as follows HPMA (I), TBAEMA (1), GMA (0.8), IIEMA (0.4), DMAEMA (0.3), 32 (0.2). Grafting yields to PE appear generally higher. 

Early reports focused on the dithiobenzoale RAFT agents (Z=Ph e.g. 171-180, Table 9.10).3S2 410 Cumyl dithiobenzoate (175) shows utility with S and (meth)acrylic monomers.38 However, retardation is an issue with the acrylates...

The compositions are liquid at room temperature and have a viscosity lower than 20cps at printing temperature, which is higher than room temperature. The curable components are generally combinations of (meth)acrylic monomers and oligomers.

Zirconocenes and lanthanocenes active for olefin polymerization do, in fact, carry out well-controlled homopolymerizations of (meth)acrylic monomers, but polymerization takes place by an enolate mechanism in which the conjugated carbonyl group plays a crucial role in stabilizing the active center. Both monometallic and bimetallic mechanisms have been documented. Collins and co-workers developed a zirconocene group-transfer polymerization (GTP) technique for the polymerization of methyl methacrylate (MMA) which utilizes a neutral zirconocene enolate as an initiator and the conjugate zirconocene cation as a catalyst (Scheme 3). ...

Among three common classes of monomers including (meth)acrylates, styrenics and acrylamides, (meth)acrylates were the most widely used because various functional polymers with hydroxyl, carboxyl, amino and other groups can be facilely obtained from the corresponding functional (meth)acrylate monomers, except the commonly used monomers of methyl methacrylate (MMA) and u-butyl methacrylate ( -BMA). 

Homopolymers A basic CPB model is a horaopolymer with a long homopolymer main chain carrying homopolymer side chains in every repeating unit. The majority of reports have employed ATRP or the anionic polymerization of a (meth)acrylate monomer for the synthesis of a homopolymer backbone. ATRP is frequently... 

Trithiocarbonates were reported as effective RAFT agents by Le et a Trithiocarbonates are less active than other RAFT CTAs, but are effective at controlling the polymerization of styrenic and meth(acrylic) monomers. Trithiocarbonates are also more easily synthesized and purified than other RAFT reagents. A wide variety of functionalized trithiocarbonates have been reported in the literature, and some are given in Table a number... 

Some of the cured materials were examined with a Perkin-Elmer 621 Grating Infrared Spectrophotometer to monitor the curing characteristics of the maleimide/meth-acrylate monomer mixtures. Thermal analysis was also performed with a Perkin-Elmer DSC-2 Differential Scanning Calorimeter and a Perkin-Elmer TMS-2 Thermomechanical Analyzer.
