Patent number: 4173693Abstract: The title compounds are of the formula P --O--R--.sub.n R').sub.mwherein:P is a polymer matrix of sufficient structure and molecular weight so as to be substantially water- and hydrocarbon-insoluble;R is --CH.sub.2 CH.sub.2 O--, --CH.sub.2 CH.sub.2 CH.sub.2 O--, ##STR1## --CH.sub.2 CH.sub.2 CH.sub.2 CH.sub.2 O- or a combination thereof; R' is hydrogen, hydrocarbyl or inertly-substituted hydrocarbyl;n is an integer of 3 to about 40; andm is a real number such that the weight percent of --O--R--.sub.n R') groups is at least about 1 percent of the total weight of the compound.A representative example of these compounds is the reaction product of a poly(ethyleneglycol ether) having a weight average molecular weight of about 300 and a chloromethylated polystyrene resin. These polymer-supported poly (alkyleneglycol ethers) are useful phase-transfer catalysts for a wide variety of reactions, such as alkylation, displacement and carbene formation.Type: GrantFiled: January 12, 1978Date of Patent: November 6, 1979Assignee: The Dow Chemical CompanyInventors: Andrew T. Au, Harold H. Freedman

Patent number: 4168369Abstract: Synthetic elastomer compositions of high green strength comprise the reaction product of a rubbery polymer of a conjugated alkadiene having a small number of aldehyde groups attached to and randomly distributed along the polymer chain, and a polyamine having at least two non-tertiary amine groups. An example is a copolymer of styrene, butadiene and cinnamaldehyde (0.5 parts by weight) reacted with p-phenylene diamine, in an amount of 1 mole diamine per mole of cinnamaldehyde.Type: GrantFiled: June 28, 1974Date of Patent: September 18, 1979Assignee: Polysar LimitedInventors: Evalds Lasis, Ernest J. Buckler
