Praetorius tested different cycloalkyl-bridged catalysts and found that the most successful at incorporating hexene comonomer is the cyclobutyl-bridged, which he says offers "greater control of hexene distribution, MWD, and long-chain branching." Next Praetorius tested the position of the bridge on the catalyst and discovered an unusual effect on molecular weight.
It is established that the surface hardness and Vicat softening temperature depend on the nature and conditions of synthesis of the polymer matrix and also on the nature of the comonomer. The addition of bifunctional GMA to the composition results in a significant increase in surface hardness and heat resistance.
This was also a butene comonomer, but with a higher base resin density of 0.939 g/cc to increase the yield strength and more consistently meet quick burst stress requirements.
The comonomer composition used is based on a commercial acrylic latex formulation where 10 wt% of the main acrylic monomer mixture was replaced by AcFAD.
that modifying the internal standards does not influence the DC of comonomer blends, and
It was shown that the introduction of ionic comonomer (SA) into the structure of PNIPA results in a similar shape of phase diagram and differences are related to the shift of minimum critical points and intersections to the lower content of gel.
The copolymers were designed to have different feed ratios of comonomer units (benzothiadiazole and triazole).
The authors further observed that an ethylene comonomer on a vinyl acetate backbone exerted the same level of hydrolytic resistance on a weight basis as VeoVa.
Furthermore, combining two reactors makes it possible to steer the MMD separately in the higher and lower MM ranges--to incorporate more branches in the longer polymer chains (inverse comonomer distribution) [6,7].
