The company expects the product, which will be sold through an existing distributor network, to be on the market in the fall of 1985. For further information, Circle 14 on Reader Service Card PRC Announces Availability Of New Family Of Mercaptan Functional Polymers Products Research & Chemical Corporation (PRC) recently announced the availability of a new family of mercaptan functional polymers called Permapol P-3. The mercaptan-termi- nated Permapol polymers were introduced to complement the hydroxy materials offered by the company. According to Herbert W. McNulty, vice president-market development, Permapol Poly- mers, Permapol P875 is the first mercaptan-ter- minated polymer to join the growing family of Permapol P3 Polymers. This family now in- cludes polyols used to make polyurethanes with resistance to hydrolysis and hydrocarbon fluids and P3 Polymers that do not have reactive end groups that are used as hydrocarbon-resistant plasticizers. Mr. McNulty said that P875 is designed for use in room temperature curing high-perform- ance sealants, adhesives and elastomers. As a component of epoxy-based fiexibilized adhe- sives, the Permapol structure imparts low-tem- perature flexibility and hydrocarbon fluid re- sistance. P875 is said to be particularly suited for for- mulations where resistance to cold-flow or com- pression-set and improved low-temperature flexibility plus adhesion to difficult substrates is desired. PRC also announced that it is erecting a grass roots plant in the Mohave Desert, Calif., to man- ufacture commercial quantities of Permapols.
