Polymerisable surfactants for polymethacrylates using catalytic chain transfer polymerisation (CCTP) combined with sulfur free-RAFT in emulsion polymerisation [PDF]

open access: yes, 2020
Statistical copolymers of methacrylic acid and methyl methacrylate were synthesised via free radical catalytic chain transfer polymerisation (CCTP) in emulsion to form a hydrophilic emulsifier/surfactant.

Methyl Methacrylate Oligomerically-Modified Clay and its Poly (Methyl Methacrylate) Nanocomposites [PDF]

open access: yes, 2005
A methyl methacrylate oligomerically-modified clay was used to prepare poly(methyl methacrylate) clay nanocomposites by melt blending and the effect of the clay loading level on the modified clay and corresponding nanocomposite was studied.

Differential orientation and conformation of surface-bound keratinocyte growth factor on (hydroxyethyl)methacrylate, (hydroxyethyl)methacrylate/methyl methacrylate, and (hydroxyethyl)methacrylate/methacrylic acid hydrogel copolymers [PDF]

open access: yesBiointerphases, 2018
The development of hydrogels for protein delivery requires protein–hydrogel interactions that cause minimal disruption of the protein’s biological activity. Biological activity can be influenced by factors such as orientational accessibility for receptor binding and conformational changes, and these factors can be influenced by the hydrogel surface ...

Bacterial Growth Kinetics under a Novel Flexible Methacrylate Dressing Serving as a Drug Delivery Vehicle for Antiseptics [PDF]

open access: yes, 2013
A flexible methacrylate powder dressing (Altrazeal®) transforms into a wound contour conforming matrix once in contact with wound exudate. We hypothesised that it may also serve as a drug delivery vehicle for antiseptics.

Terpolymerization kinetics of methyl methacrylate or styrene/dodecyl methacrylate/octadecyl methacrylate systems [PDF]

open access: yesPolymer International, 2006
AbstractThis study describes low‐conversion terpolymerization kinetic investigations of methyl methacrylate/dodecyl methacrylate/octadecyl methacrylate (MMA/DDMA/ODMA) and styrene/dodecyl methacrylate/octadecyl methacrylate (ST/DDMA/ODMA) systems. Terpolymerizations were performed isothermally (70–105 °C), in 1 mol dm−3 xylene solutions, using 0.01 mol

Preparation of Wool-g-Glycidyl Methacrylate with a Constructed –SH Groups/Ammonium Persulfate Redox System and Characterization

open access: yesMedžiagotyra, 2022
To explore suitable synthesis parameters of efficient graft copolymerization on wool, the disulfide bonds in wool chains were reduced to sulfhydryl groups by the treatment of thioglycolic acid to wool, and then wool-g-poly(glycidyl methacrylate) was ...
