Abstract
Polymers are produced by reacting a masked polyisocyanate, which is the adduct of a polyisocyanate and a tertiary alcohol, secondary aromatic amine, mercaptan, lactam, monohydric phenol, imide or compound containing enolizable hydrogen, with a substance having a plurality of radicals containing reactive hydrogen selected from the amide, ureylene, carbamic, hydroxyl, carboxyl or amino groups, particularly the elastomeric diisocyanate modified polyesters and polyesteramides described in Specifications 694,978, 694,982, 696,449 and 696,450. The adducts used are described in Specifications 701,548, 701,459, 701,711, 701,712, 709,288, 710,122 and 716,194. The use of the adducts, which dissociate at raised temperatures, enables the rate of reaction of the polyisocyanates, and hence of the curing and crosslinking of the elastomers refined to, to be controlled. The Specification lists many examples of the following groups of substances, in addition to the elastomers referred to, which may be reacted with the masked isocyanates to give polymers:-polyhydric alcohols, polyamines, polycarboxylic acids, amino alcohols, amino-carboxylic acids and hydroxy-carboxylic acids. In examples: (13) 100 parts of a rubber-like polymer which is a polyester of acid number 3.5 and hydroxyl number 58.6 from adipic acid, ethylene glycol and propylene glycol modified with 4.41 diphenylene diisocyanate, is mixed on a rubber mill with 8.19 parts of the adduct of epsilon caprolactam and 4.41 diphenylene diisocyanate. Test sheets were heated at 248 DEG F. for 26 hours and then press cured for 35 minutes at 300 DEG F. (14) As in 13 but using 9.45 parts of the adduct from 2-mercaptobenzthiazole and press curing for 70 minutes at 300 DEG F. (15) As in (14) but using 8.48 parts of the adduct from succinimide. (16) As in (13) but using a polyester modified with 1.5 naphthalene diisocyanate, 12.2 parts of the adduct from 1.5 naphthalene, diisocyanate and diethyl malonate, heating for 2 hours at 300 DEG F. and press curing for one hour at 300 DEG F. Figures are given for the mechanical properties of the cured rubbers of the examples and comparative figures for the degree of cross-linking after 2 and 5 days of the uncured rubber of examples 13, 14 and 15 in the presence of masked isocyanates and of the uncured rubber of example 13 in the presence of 4.41 diphenylene diisocyanate.
