Abstract: The disclosure relates to a curable polymer composition comprising (i) a copolymer of a diisoalkenylarene (DIAEA) and a divinylarene (DVA), and (ii) at least one anti-scorching agent. The copolymer has a solubility in a hydrocarbon solvent at 25° C. for a period of less than 4 hours of at least 10 wt. %, a glass transition temperature (Tg) of 50 to 300° C., and a Gel Content of less than 5 wt. %. The curable polymer composition is cured at a temperature of greater than 140° C. to obtain a cured polymer composition having a Gel Content in a hydrocarbon solvent of >90%, and low Dk and Df values. The curable polymer composition does not cross-link or has minimal premature cross-linking in steps such as processing, storage, etc., and can be used in copper clad lamination applications.

Abstract: An associative rheology modifier is obtained by coupling of a rheology modifier precursor with a coupling agent. The rheology modifier precursor is formed by reacting a rosin acid with a polyether at a mole ratio of the rosin acid to the polyether of >2:1, at a temperature from 180-350° C. and in the presence of an acid catalyst. The polyether has a molecular weight of 500-10,000 g/mol and the rheology modifier precursor has a water solubility of >10 wt. % concentration. The associative rheology modifier has a molecular weight (Mw) from 1500-25,000 g/mol. The associative rheology modifier shows a high shear thinning effect at low shear rate. A composition is also provided comprising the associative rheology modifier.

Abstract: The bra with hot/cold inserts is a therapeutic device in the form of a vest-like elastic garment adapted to be worn on the human upper torso. The device includes front panels having pockets therein for retaining gel packs. The device is effective in providing warm or cold therapy to the chest and rib areas. The garment can be used by humans of both genders.
